322 PM EDT Fri Apr 7 2023 Blustery northwest winds will relax tonight as high pressure builds into the region from the west.
259 PM EDT Fri Apr 7 2023 A very weak cold front sweeps southeastward through our region early this morning. Behind the front, a high pressure ridge affects our region through this weekend as the core of the ridge moves from the Upper Midwest toward the Mid-Atlantic states. The weather will be nice and quiet for this Easter weekend thanks to high pressure. The center of this high pressure system is currently located near the Upper Great Lakes region and will slowly shift eastward tonight towards the Eastern Great Lakes region. We will have sunny skies on Saturday but tomorrow's highs will still be just a few degrees cooler than our average for early April in the lower to middle 50s.
107 PM EDT Fri Apr 7 2023 A cold front will move south and east of southern New York and New England today with brisk and colder than normal conditions. High pressure builds in from the Great Lakes Region and southeast Canada with diminishing winds and cold conditions tonight. Tonight the winds should diminish with a weakening pressure gradient and a stabilizing boundary layer, as high pressure builds in.
(This evening through Saturday) A weak upper level trough will slowly approach West Central Texas from the west late this afternoon and into the overnight hours. Quite a bit of uncertainty remains on exactly how much coverage of showers that we will see later this afternoon, with the higher rain chances continuing across our southeast counties.
With some warm advection overnight, we'll keep the warmer temperatures planned for tomorrow but if the cloud cover thickens too early, we may be several degrees too high.
1212 PM CDT Fri Apr 7 2023 After chilly early morning low temperatures ranging from the upper 20s in the Illinois River Valley to the middle to upper 30s south of I-70, ample sunshine will boost afternoon highs into the lower 60s across central Illinois today. Meanwhile a thick blanket of high clouds is keeping readings in the lower 40s across the far SE KILX CWA around Flora and Lawrenceville. Given ample sunshine efficiently heating the dry airmass, high temperatures will top out near seasonal normals in the lower 60s. Surface ridging will dominate the weather across central Illinois this weekend, resulting in plenty of sunshine and warming temperatures.
18z surface analysis showed very broad high pressure centered over the Great Lakes, with southerly winds occasionally gusting around 20 MPH. [Key Message] 1) High pressure keeps us quiet to start the weekend with milder temperatures [Discussion] The aforementioned high pressure will keep our region in quiet weather with plenty of sunshine to start the weekend. Persistent southerly flow across the Midwest will help keep our temperatures near normal values for early April, with lows tonight dropping only into upper 30s and highs for Saturday climbing into the low to mid 60s.
High pressure remains in control of the weather pattern today through tomorrow.
107 PM CDT Fri Apr 7 2023 (Today through Saturday) High pressure at the surface and west-southwesterly flow aloft persist today through Saturday.
518 PM CDT Fri Apr 7 2023 (Tonight) A cold front that moved across the area yesterday was well to our south and east, extending from the Gulf coast south of New Orleans to east of Atlanta and near the NC/SC coastal border. As noted earlier, colder conditions reigned this afternoon with readings raining from the upper 40s southern middle TN, to around 50 NW AL and in the lower 60s NE AL (where the coldest air has quite made it).
746 PM EDT Fri Apr 7 2023 High pressure and dry air have dominated the central and western portions of Upper Michigan today. The highest snow totals can be expected south of Menominee toward Green Bay, but 2-4 inches can't be ruled out for Menominee proper.
Showers and isolated thunderstorms developed this afternoon and early evening in response to an upper level trough moving overhead. Showers will decrease overnight, but a few snow showers will continue over the central Idaho mountains through early Saturday morning as the trough exits the region. Models depict patchy valley fog developing overnight, mainly in snow- covered mountain valleys or areas that saw significant rainfall today, such as the Lower Treasure Valley. Weak upper level ridging and dry conditions will allow temperatures to warm 5 to 10 degrees on Saturday from today's values.
The near term forecast kicks off by a cold front that has now stalled generally along the I-85 corridor. Any updrafts in strong storms that get going could be maintained today, however, the severe weather threat will remain on the low end.
1019 PM EDT Fri Apr 7 2023 Blustery northwest winds will relax tonight as high pressure builds into the region from the west.
rain will increase across the south and move east as a low pressure system develops across the trailing boundary and moves through Alabama. but as the front and cooler air moves into the state.
715 PM CDT Fri Apr 7 2023 Through Saturday: A cold front which has been festering over the region for days will finally begin to make better southward progress tonight into Saturday, with an end to the rain finally in sight.
5 inches of rain has fallen over the past 12 hrs, with the highest amounts for locations north of I-10.
Most of the CAMs has the highest precipitation falling near the Clark and Taylor county line.
538 PM MDT Fri Apr 7 2023 Upper ridge over the high Plains with trof over Pacific NW and extensive cloud cover west of ridge axis, while skies remain clear over forecast area. On the surface, trof/stationary front remains from northwestern MT-south central SD with southeast winds and temperatures in the 40s to the east and southwest winds and temperatures mainly in the 50s to the west, although southeast winds around the eastern-northern slopes of the Black Hills coming off deeper snowcover have kept temps lower. The inversion will persist over west central SD through Saturday, where the temperatures will remain cooler than the rest of the area. Temperatures will warm to above Mon and Tue as a thermal ridge builds over the high Plains, then a cold front moving southward on Wed will bring cooler temps.
High pressure over the Atlantic water will weaken on Saturday ahead of a cold front approaching from the northwest. The high pressure is promoting moderate winds across the coastal waters, but winds will slacken to light to gentle tomorrow.
648 PM EDT Fri Apr 7 2023 A very weak cold front sweeps southeastward through our region early this morning. Behind the front, a high pressure ridge affects our region through this weekend as the core of the ridge moves from the Upper Midwest toward the Mid-Atlantic states. The weather will be nice and quiet for this Easter weekend thanks to high pressure. The center of this high pressure system is currently located near the Upper Great Lakes region and will slowly shift eastward tonight towards the Eastern Great Lakes region. We will have sunny skies on Saturday but tomorrow's highs will still be just a few degrees cooler than our average for early April in the lower to middle 50s.
This is all due to continued overrunning, which may actually intensify late tonight into early Saturday in our southeast counties as surface ridging/cold air damming works westward thru north GA and into east AL. Northeast flow will remain rather persistent as well, and as a result of rain cooled air, temperatures are running a few degrees cooler than earlier forecast.
705 PM EDT Fri Apr 7 2023 High pressure over the Great Lakes allows for mostly sunny skies this weekend with high temperatures only a degree or two below normal. Overnight lows drop to the low 30s in the north, upper 30s in the south. High pressure slowly moving off toward New England, but remains the dominant weather influencer for the area. Mass subsidence and dry air in the low levels combine to keep Saturday mostly sunny, with perhaps a few high clouds. The high will get shunted eastwards as a subtropical low moves into the Gulf Coast late in the week. While this low will stay well south of the area, moisture from it will likely get drawn into the Ohio Valley.
745 PM EDT Fri Apr 7 2023 High pressure builds in from the Great Lakes Region and southeast Canada with diminishing winds and cold conditions tonight. Based on satellite trends and sources of guidance/ensembles, the high clouds will build east and south through the night, with clearing reaching the mid Hudson Valley and NW CT by daybreak. Highs Saturday around 50 to mid 50s and cooler in higher terrain.
618 PM CDT Fri Apr 7 2023 (Tonight through Saturday night) Upper level trough axis extending from the southwest CONUS southeastward into northeast Mexico is producing a southwest flow aloft over South-Central Texas. High temperatures are forecast to come up to the 60s and 70s after a cooler pattern the past few days.
Weak mid/upper level ridging over the Rockies today is progged to translate downstream over the central CONUS on Saturday.
922 PM EDT Fri Apr 7 2023 High pressure over the Great Lakes allows for mostly sunny skies this weekend with high temperatures only a degree or two below normal. High pressure slowly moving off toward New England, but remains the dominant weather influencer for the area. Mass subsidence and dry air in the low levels combine to keep Saturday mostly sunny, with perhaps a few high clouds. The high will get shunted eastwards as a subtropical low moves into the Gulf Coast late in the week. While this low will stay well south of the area, moisture from it will likely get drawn into the Ohio Valley.
could briefly reach close to freezing. (Saturday through Friday) Weak mid level trough axis that has been lingering across southern New Mexico and providing upper level cloud cover to the eastern and southern parts of the forecast area recently will slowly drift eastward by Saturday, leaving behind clear skies. The surface will still be under the influence of surface ridging as it slowly slides east as well during the day.
Cannot entirely rule out a bit of fog across our south or southwestern zones around sunrise where winds will be returning to a more easterly direction in closer proximity to a dissipating frontal zone, but will refrain from introducing this low potential in the public forecast at this time. Overcast areas to the south could be held to the low to mid 60s for highs.
1027 PM EDT Fri Apr 7 2023 High pressure builds in from the Great Lakes Region and southeast Canada with diminishing winds and cold conditions tonight. Based on satellite trends and sources of guidance/ensembles, the high clouds will build east and south through the night, with clearing reaching the mid Hudson Valley and NW CT by daybreak. Highs Saturday around 50 to mid 50s and cooler in higher terrain.
A surface cold front lies to the southeast. Discussion: We start the period with a slow moving surface cold front just to our southeast. The upper flow is currently from the SW but will become more zonal during the period, and the cold front will gradually sag farther southeast.
On Saturday, a surface cold front will begin to approach from the north as local high pressure breaks down.
739 PM EDT Fri Apr 7 2023 Blustery northwest winds will relax tonight as high pressure builds into the region from the west.
655 PM CDT Fri Apr 7 2023 (This evening through Saturday) A weak upper level trough will slowly approach West Central Texas from the west late this afternoon and into the overnight hours. Quite a bit of uncertainty remains on exactly how much coverage of showers that we will see later this afternoon, with the higher rain chances continuing across our southeast counties.
622 PM CDT Fri Apr 7 2023 Key Messages: - Warmer and dry weather expected this weekend.
708 PM EDT Fri Apr 7 2023 VFR clear sky holds this evening across Lower Mi with light easterly wind thanks to the firm grasp of high pressure on the Great Lakes. Farther west, low pressure from Rockies into the Plains has a warm front extending into the Midwest north of which bands of mid level clouds are developing. Broad and deep subsidence over the region maintains cloud- free skies and allows high pressure to continue building in through the rest of this evening. Wind remains very light, veering from north to southeast as the center of the high passes just to our north. The absence of northerly flow will allow temps to take a step upward with highs mainly in the lower 50s - cooler readings near the lakeshore.
751 PM EDT Fri Apr 7 2023 High pressure builds in from the Great Lakes Region and southeast Canada with diminishing winds and cold conditions tonight. Based on satellite trends and sources of guidance/ensembles, the high clouds will build east and south through the night, with clearing reaching the mid Hudson Valley and NW CT by daybreak. Highs Saturday around 50 to mid 50s and cooler in higher terrain.
745 PM EDT Fri Apr 7 2023 Blustery northwest winds will relax tonight as high pressure builds into the region from the west.
Cold high pressure over the Great Lakes will extend down the eastern seaboard into our region supplying the cold temperatures through the weekend.
Saturday given the low confidence in the HREF ensembles of the combo of RH values below 15% and winds over 25 kts I elected to hold off on a fire weather headline at this point. CAM models are also trending warmer so I added a couple degrees for highs with mid to upper 70s across the region. Lows will be in the lower to mid 40s. Overall kept the POPs in with the highest chances in the east.
High pressure over the northeast CONUS will maintain dry conditions through the weekend. Latest model consensus shows high pressure / upper ridging remaining the dominant feature in the extended, maintaining dry conditions and continuing the warming trend.
(Today and tonight) Upper trough will move through the Rockies late today and tonight, and in advance of this pressure falls will occur across the High Plains with a return of south winds across the area. This will promote a continuation of warming trend with most locales climbing into the low to middle 70s this afternoon. The south winds, along with developing cloud cover will also aid in keeping overnight temperatures a bit warmer as we go through the night Saturday night, especially across the northwest where temperatures have been dropping down into the 30s last couple of nights.
329 AM EDT Sat Apr 8 2023 Expansive high pressure will ease across our region over the weekend. and into the lower to mid 40s across the North Country.
333 AM CDT Sat Apr 8 2023 Warmer and dry weather is expected through the short term. Lee side troughing will bring down sloping winds to the plains of Montana increasing temperatures out west. A strengthened low-level thermal ridge will span from eastern Montana into South Dakota. Sunday a strong upper level ridge will traverse across the Northern Rockies bringing a substantial warm up. These warmer temperatures are going to bleed over into western North Dakota leading to high temperatures in the 50s in the northwest to lower 60s in the southwest.
930 PM PDT Fri Apr 7 2023 A weak trough will move over the West Coast though Saturday, with patchy clouds at times, and slight cooling.
1201 AM CDT Sat Apr 8 2023 Key Messages: - Warmer and dry weather expected this weekend.
310 AM EDT Sat Apr 8 2023 A high pressure ridge affects our region this weekend through at least the middle of the upcoming week. Simultaneously, the core of the ridge should move from the eastern Great Lakes and vicinity to the southern Appalachians. At the surface, a stabilizing high pressure ridge continues to affect our CWA as the core of the ridge lingers in vicinity of Lake Huron and the Lower Great Lakes. Low temperatures overnight tonight should reach mainly the lower to mid 30's around daybreak Sunday, but upper 20's are expected in interior NW PA as clearing sky, weak surface winds, and low humidity promote efficient radiational cooling. Net low-level WAA accompanying the ridge will contribute to a warmer day on Sunday.
405 AM EDT Sat Apr 8 2023 A beautiful weekend is on tap for the North Country as high pressure settles over the region.
Any lingering showers will exit eastward through the overnight, bringing a dry but chilly Easter morning as low temperatures dip largely into the lower 40s. The CAD wedge will remain in place at the surface on Sunday, keeping cooler than normal temperatures on the docket amid a continued northeasterly breeze.
High pressure and drier conditions will move in later this afternoon and continue through tonight.
1055 PM MDT Fri Apr 7 2023 Upper ridge over the high Plains with trof over Pacific NW and extensive cloud cover west of ridge axis, while skies remain clear over forecast area. On the surface, trof/stationary front remains from northwestern MT-south central SD with southeast winds and temperatures in the 40s to the east and southwest winds and temperatures mainly in the 50s to the west, although southeast winds around the eastern-northern slopes of the Black Hills coming off deeper snowcover have kept temps lower. The inversion will persist over west central SD through Saturday, where the temperatures will remain cooler than the rest of the area. Temperatures will warm to above Mon and Tue as a thermal ridge builds over the high Plains, then a cold front moving southward on Wed will bring cooler temps.
Saturday will also be cool and dry with high temps in the lower 60s as a H2 trough remains over the FA. While the trough begins to depart across the northeast CONUS on Sunday, H5 zonal flow will begin to become more amplified as a ridge of high pressure builds into the FA. The models evolve a Rex blocking pattern by mid week, effectuating a dry and warming forecast. The 12Z deterministic GFS centers the surface and upper highs directly overhead by 18Z Wed. The Rex block shows signs of yielding to the low pressure system to the south by then, but the ensemble/model blending is not picking up on that yet wrt pops; won't be surprised to see a late week or early weekend pop show up with time.
Currently - The last vestiges of an Atlantic ridge reaching across Florida continues to generate gentle to moderate easterly breezes across the Keys. The deep layered ridge across the broader area is also hanging on by a thread. A cold front will progress southwards across Florida today. An exceptionally high degree of uncertainty remains regarding how far this cold front will push.
202 AM EDT Sat Apr 8 2023 High pressure builds in from the Great Lakes Region and southeast Canada with diminishing winds and cold conditions tonight. At the surface, high pressure will continue to build in, resulting in a mostly clear and tranquil day with lighter winds compared with yesterday. Highs today are expected to range from the low 40s to low 50s, a bit short of seasonal climatology. High pressure will continue to be in control tonight, which should set up ideal radiational cooling conditions. Highs Saturday around 50 to mid 50s and cooler in higher terrain.
114 AM EDT Sat Apr 8 2023 Blustery northwest winds will relax tonight as high pressure builds into the region from the west. High pressure and broad anticyclonic flow through the mid levels will provide us with continued fair weather and a trend towards lighter winds through the next 36 hours. While the center of the ridge of high pressure will remain to our west through the period, the pressure gradient will relax beginning tonight with large pressure rises occurring. Given the cooler start to the day compared to today, highs look to be roughly the same or lower despite a moderating air mass, generally from the upper 30s to mid 40s.
Light S/SE surface winds with filtered sunshine as high clouds gradually increase from the west will make for a beautiful Spring day area wide, with temperatures in the low to mid 70s. By late tomorrow night into early Sunday morning, upper troughing to the north will deepen southward into eastern New Mexico. S/SE surface flow out ahead of the developing upper trough is expected to lift dewpoints over the southwest Texas Panhandle and the western South Plains around 10 to 15 degrees from low 30s to mid 40s by midnight tonight in most spots on the Caprock. The lift associated with the upper trough working eastward over improved boundary layer moisture will provide chance/slight chance shower and thunderstorms overnight tonight into Sunday morning.
131 AM EDT Sat Apr 8 2023 High pressure over the Great Lakes allows for mostly sunny skies this weekend with high temperatures only a degree or two below normal. High pressure slowly moving off toward New England, but remains the dominant weather influencer for the area. Mass subsidence and dry air in the low levels combine to keep Saturday mostly sunny, with perhaps a few high clouds. The high will get shunted eastwards as a subtropical low moves into the Gulf Coast late in the week. While this low will stay well south of the area, moisture from it will likely get drawn into the Ohio Valley.
Temperatures trends Saturday will see the warming trend resume area wide as a stronger upper level ridge centered over the lower Colorado river valley amplifies and builds in earnest across the southwest US. Highs Saturday will range from the lower 50s to the upper 60s with overnight lows in the upper 20s to upper 30s. Sunday will be warmer still with daytime temperatures ranging in the upper 50s to upper 60s also many lower elevation valleys will be seeing their first 70+ degree day this year. Overnight low will remain above freezing for most lower elevation valleys as temperatures range in the upper 20s to upper 30s.
As such, highs today and tomorrow will range in the low to mid-70s, with lows tonight ranging in the low-50s.
(Today through Sunday) High pressure lingers at the surface while westerly flow aloft today becomes northwesterly Sunday. An upper level trough and associated weakening cluster of showers with isolated thunderstorms over our Central Texas counties will move off to the east early this morning.
Mid level ridging will build over the region through Saturday, with milder temperatures, and virtually no chance for pcpn as the airmass is quite dry. Saturday night brings passage of a trof aloft, but even then chances for any measurable pcpn look scant at best. Deterministic EC is a bit cooler, but still rather warm.
Another weak trough may pass through Sunday night, though precipitation does not appear likely at this time.
103 AM CDT Sat Apr 8 2023 (This evening through Saturday) A weak upper level trough will slowly approach West Central Texas from the west late this afternoon and into the overnight hours. Quite a bit of uncertainty remains on exactly how much coverage of showers that we will see later this afternoon, with the higher rain chances continuing across our southeast counties.
At the surface, high pressure will largely remain over the Great Lakes as it slowly builds east through the period. Otherwise, temperatures look to warm into the low to mid 40s for most areas this afternoon before cooling back into the 20s overnight.
Dewpoints rising tonight due to slight easterly shift in low-level winds will cause slightly warmer lows in the low to mid 60s.
After the high clouds move out, this will the focus area for clouds the rest of the day, with mostly clear skies north of there.
High pressure will maintain dry conditions, light wind, and seasonable temperatures through the weekend.
Local vorticity maximum will interact with this warm front tonight and create a slight potential for rain mainly for Western Wisconsin. The NBM has been more aggressive with kicking PoPs back towards the Twin Cities however reluctant to follow suit given the dry environment in the lower levels as shown in forecast soundings. 20", with the highest amounts focus from Eau Claire, WI and eastward. This weekend, the developing ridge will enter our region for Saturday making it a tranquil day with highs ranging in the 60s south and mid to upper 40s in the snowpack northwest.
309 AM EDT Sat Apr 8 2023 A beautiful weekend is on tap for the North Country as high pressure settles over the region.
Near Lake Michigan, temperatures will be cooler, with highs only reaching into the mid to upper 60s and low 70s.
