With upper ridging in place today, temperatures will climb into the upper 30s to mid 40s over areas with deep snow pack. The waa will be focused around a warm front that will stretch from North Platte, NE to just south of Brookings this afternoon. Southerly sfc winds across the east will also help usher in warmer air. The upper trough will actually not do much to suppress heights. With little mxing on Sunday it's hard to see how temperatures will be even warmer than today, but all guidance points to highs in the 40s to 60s. Ensemble models offer a possible reason of a strong upper ridge building in faster than deterministic model solutions suggest. A building upper ridge will translate from the Western CONUS into the Plains and Nation's mid-section through the first half of the period.
High pressure then remains in control through the middle of the week. Strong cold front has pushed south through the forecast area and currently located from near GGE to MCN. Hi-res guidance suggests this band of rain will persist through the evening and then rain will expand across the entire area after 06z as isentropic lift increases with an upper trough approaching from the west. Although some models have trended slightly warmer, there is still the potential of record low high temperatures.
On Sunday, precipitation will exit our area as a broad area of high pressure builds over the the Ohio and Tennessee Valleys.
High pressure anchored over the Great Lakes will continue to dominate the weather today. The sun will efficiently heat the dry airmass, resulting in high temperatures a couple of degrees warmer than yesterday in the middle 60s.
358 AM EDT Sat Apr 8 2023 High pressure over the Great Lakes will allow for dry weather this weekend with high temperatures only a degree or two below normal. Temperatures will warm slightly within a couple degrees of normal, with highs from the upper 50s north to the lower 60s south. Large area of high pressure to continue building slowly east to the Eastern Great Lake and New England overnight. Forecast high temperatures in the lower and middle 60s. High pressure retrogrades back toward the Ohio Valley to start the week. Weak southerly flow develops with the high centered nearby bringing warm, clear conditions for the first half of the week.
An increasing nocturnal low level jet will help advect moisture back into the area tonight, keeping overnight lows warmer along and east of I-20.
320 AM EDT Sat Apr 8 2023 Upper ridging continue to stretch over the area from the Yucatan Channel into the W Atlantic while an upper trough swings from the S Plains in the MS River Valley today. At the surface, high pressure remains in control for 1 more day with very warm conditions and a few late afternoon sea breeze showers or storms over inland areas. The cold front is expected to slowly move into the C FL Peninsula tonight the S FL Sunday with a chance of showers or storms for much of the area bringing much needed rainfall to some areas. Behind the front cooler high pressure will build into N zones tonight then the rest of the areas Sunday. Model guidance diverge but depicts the upper troughiness over the E U.
Lows tonight will fall slightly into the low to mid 60s for most locations. Easter Sunday is expected to be mild with highs in the low to mid 70s.
1234 AM CDT Sat Apr 8 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.
High pressure ridging will remain the dominant influence leading to a continuation of the quiet conditions during the period.
Some drizzle/light rain has managed to overcome the drier air in the low levels across western Wisconsin as we head into the early morning hours. Temperatures will remain in the low 60s south/east to upper 40s north/west.
1239 AM CDT Sat Apr 8 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.
Prominent ridging aloft building over the mid-section, will shift eastward, pushing the precipitation out of the area. By the end of the short term, the ridge axis will be located about the Central Plains. But before that occurs, we must get through another day of highs struggling to reach the 60s in the Valley and 50s in the higher elevations. Due to the cooler temperatures, flakes may mix with rain in the highest elevations.
Winds will shift northeasterly to easterly throughout the day as the aforementioned high pressure continues northeast.
120 AM MDT Sat Apr 8 2023 The upper ridge axis is centered over the CONUS, with a trough moving through the west.
2) Isolated to scattered mountain showers possible with some isolated sprinkles and briefly gusty winds possible for the adjacent lower elevations The upper trough across the western U. Lapse rates are steep enough to support an isolated embedded thunderstorm or two, particularly across northern and western portions of the area which could produce a quick inch or two of snow across the higher peaks. As the upper trough translates eastward across the plains this evening, a few showers will drift off into the adjacent plains. These should push eastward and end during the evening with a cold front pushing through the plains overnight behind the departing trough. Upper-level ridging will build into the area starting on Sunday.
Cooler readings are expected for today with a wedge of cooler air pushing in from the NE.
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.

Inverted trough associated with a low pressure system near the Gulf of Mexico pushes its cirrus shield northward toward our area. Temperatures will warm slightly within a couple degrees of normal, with highs from the upper 50s north to the lower 60s south. Large area of high pressure to continue building slowly east to the Eastern Great Lake and New England overnight. Forecast high temperatures in the lower and middle 60s. High pressure retrogrades back toward the Ohio Valley to start the week. Weak southerly flow develops with the high centered nearby bringing warm, clear conditions for the first half of the week.
958 AM EDT Sat Apr 8 2023 Showers continue to meander across the region northwest of the front along a weak trough. Prominent ridging aloft building over the mid-section, will shift eastward, pushing the precipitation out of the area. By the end of the short term, the ridge axis will be located about the Central Plains. But before that occurs, we must get through another day of highs struggling to reach the 60s in the Valley and 50s in the higher elevations. Due to the cooler temperatures, flakes may mix with rain in the highest elevations.
1047 AM EDT Sat Apr 8 2023 Expansive high pressure will be centered over our region this Easter weekend. and into the lower to mid 40s across the North Country.
615 AM CDT Sat Apr 8 2023 (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.
629 AM EDT Sat Apr 8 2023 High pressure will build in and result in mostly sunny skies and seasonable temperatures this weekend. 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. Midlevel trough will pass through with little fanfare early Sunday, with height rises building in quickly behind it. At the surface, high pressure will hold firm, resulting in another sunny and calm day.
Thereafter, a building ridge of high pressure will support a continued warming trend, with highs Sun breaking into the 60s across the ern Magic Valley and Raft River region.

947 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.
1021 AM EDT Sat Apr 8 2023 High pressure will build in and result in mostly sunny skies and seasonable temperatures this weekend. With the high pressure building into the area, strong subsidence is allowing for dry and sunny conditions. With the high pressure close to the area, it will continue to be a tranquil day with lighter winds compared with yesterday. Despite the abundant sunshine, 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. Midlevel trough will pass through with little fanfare early Sunday, with height rises building in quickly behind it. At the surface, high pressure will hold firm, resulting in another sunny and calm day.
Otherwise, temperatures are almost a mirrored copy of yesterday's at this time with readings in the lower to mid 80s. This feature will begin moving southward later today as a cold front but how ultimately far south it will trek remains uncertain and will bear worth watching. Meanwhile, a cold front will gradually approach from the north.
627 AM CDT Sat Apr 8 2023 (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.

Temperature minimums will range from the lower 40s into the 50s tonight under mostly clear skies (nearly clear north of I-30) as a result of surface ridging. By tomorrow, cloud cover redevelops, continuing to moderate temperatures into the lower 70s.
(18Z TAFS) IFR to LIFR ceilings will slowly overspread the area from as the cold front moves across the area. As the surface circulation moves east of the area, northerly flow will bring a bit cooler air south over the forecast area for tonight and Sunday. The influx of cooler air is greatly reduced in the process, and when combined with more sun, temperatures are expected to top out in the upper 60s, below seasonal norms.
115 PM EDT Sat Apr 8 2023 A beautiful weekend is on tap for the North Country as high pressure settles over the region.
238 PM EDT Sat Apr 8 2023 High pressure will remain overhead through early in the work week. Then, high pressure shifts south during the middle portion of the week keeping a warm and dry air mass. After a chilly start, Easter Sunday will be pleasant temperature wise with 50s west of the Blue Ridge and near 60 to the east with full sunshine.
Clouds continue to blanket the region as modest cold air advection persists on northerly winds, while a high pressure ridge northwest of the area tries to slowly build southeast. With temps currently cooler than expected, adjusted hourly grids through the afternoon, lowering slightly from the previous forecast, and also adjusted Max Temps down slightly as well.
Tomorrow will be warmer than today with highs in the upper 60s to lower 70s. Borchardt Upper level ridge over the western U.
(The rest of Today and Tonight) Five star weather will continue through the rest of the day and into tonight under the influence of modest surface and mid level ridging. Clear skies and light easterly winds will prevail, with low humidities allowing temps to top out in the lower to mid 70s later this afternoon across the region. Most locations will see lows in the lower to mid 40s, with a few of the normally cooler locations dipping down into the mid to upper 30s for lows tonight.
With upper ridging in place today, temperatures will climb into the upper 30s to mid 40s over areas with deep snow pack.

328 PM CDT Sat Apr 8 2023 Latest surface analysis shows a warm front draped across western SD, then near/along the FSD/ABR CWA border and on into southern MN. Will also be watching a weak wave of low pressure along the frontal boundary with potential for a few light showers across the southeast CWA by Sunday morning. Although, it appears some warmer readings near 60 are possible across the west-river counties where snowpack has dwindled. Models are in great agreement with building the seasons first strong ridge and plenty of warm air with it.
301 PM EDT Sat Apr 8 2023 High pressure sprawled across the Great Lakes and Northeast will keep us dry with a northeast breeze through the short term.
(This afternoon through Sunday night) Satellite shows the low clouds that developed along the Trans Pecos this morning quickly dissipating, and temperatures warm this afternoon to the low to mid 70s under mostly sunny skies. On Sunday, the thermal ridge is positioned just to the west of the region and temperatures respond, giving highs in the 70s and 80s for Easter Sunday. Outdoor activities may be impacted, however, as a positively tilted trough moves across the Panhandle of Texas, likely bringing some storms to the area Sunday afternoon and evening. Models are pushing timing of the development of storms later on in the newest runs, likely in response to the slower track of the trough and the need for afternoon heating.
Mesonet temperatures are running a few degrees warmer than yesterday's values and the morning RAOBs supported this minor increase.
Amid high pressure and light nely sfc wind, general sun and only passing high clouds today will prevail with a notable decrease in humidity as deep mixing ensues and taps into abundant dry air above 900mb. A Rex block pattern across central North America will maintain the status quo as low pressure advances slowly inland/nwd from the Gulf of Mexico. A broad warm sector sandwiched between the ern-CONUS ridge axis and wrn-CONUS trough will supply unseasonably warm air into the Upper Ohio Valley.

253 PM CDT Sat Apr 8 2023 Continued dry and progressively warmer weather is anticipated for the remainder of the weekend.
327 PM EDT Sat Apr 8 2023 High pressure continues to be the primary weather influencer for the area. Sunday arrives sunny and a bit chilly, with temperatures in the 30s but ample daytime heating will help bring temperatures up to the low to mid 60s by afternoon. High pressure begins to retrograde back toward the area Sunday night, keeping clear skies and weak winds in place. A longwave H5 ridge becomes the predominant upper level feature by mid week, with higher heights leading to an additional surge in warmer air across the Ohio Valley.
A trough along the coast this morning will weaken as it comes inland, with clouds increasing mainly across northern areas this afternoon and tonight, then decreasing toward morning.
As we go into mid/late week, an upper level trough digging southward into the Gulf of Mexico is expected to induce cyclogenesis along an unusually southward displaced frontal boundary.
122 PM EDT Sat Apr 8 2023 High pressure over the Great Lakes will allow for dry weather this weekend with high temperatures only a degree or two below normal.
