610 PM CDT Fri Apr 5 2024 (Tonight) Temperatures continue to stay on the cooler side this afternoon, currently ranging from the upper 40s to mid 50s. This is about 15-20 degrees below seasonal norms, which are typically in the lower 70s during early April.
(Through Tonight) A series of dry cold frontal and trough passages through tonight will keep NW winds elevated at 5-10 mph inland and 10-15 mph along the Atlantic Coast and the winds will slowly veer to the North by the early morning hours on Saturday. The next shot of cooler air pushing in tonight under clear skies will push Min Temps down to below normal levels once again, with widespread 40s over inland areas and near 50 degrees along the Atlantic Coast.
(Tonight) No major changes needed to the ongoing forecast this Fri evening, as a large area of high pressure continues to build eastward into the Midwest/OH Valley states. The wind flow should diminish a bit more overnight, with lows falling into the mid 30s for most spots, except NE AL where lows may reach the lower 30s.
610 PM CDT Fri Apr 5 2024 - Low temperatures will drop below freezing tonight.
558 PM EDT Fri Apr 5 2024 Deep low pressure spinning over Down East Maine will maintain breezy and cool conditions into Saturday with rain and snow showers that will diminish overnight. However, low level instability under the upper trough, combined with upslope flow, will likely yield lingering snow showers across the N Mtns through the night with minimal if any additional accumulation. The upper low is finally progged to push out to sea by the second half of the weekend.
Temperatures will be in the low to mid 40s tonight. (Through Saturday) A reinforcing cold front moved through the region this afternoon. This will lead to a continuation of cooler and drier conditions tonight into Saturday with lows dipping into the lower to middle 40s and highs reaching into the upper 60s to lower 70s.
(The rest of tonight) Pressure gradient at the surface will tighten during the overnight hours in response to approaching low pressure. Strong negatively tilted upper trough will swing into the central Plains during the day Saturday. Still the potential for a few marginally severe storms during this time period given the low CAPE/high shear environment.
628 PM CDT Fri Apr 5 2024 - Quiet weather for the start of the weekend with high temperatures Saturday reaching to the low to mid 50s.
849 PM EDT Fri Apr 5 2024 Large closed low along the New England/Canadian maritimes will continue to churn very slowly over that area through Saturday.
627 PM CDT Fri Apr 5 2024 (This evening through Saturday) Fire weather, storms, and strong winds are all in the forecast for Saturday as an upper level low treks through the central plains. ***Fire Weather*** The aforementioned winds will combine with RH values in the low teens (and probably a few single digit RHs in our far western counties) to create critical to extreme fire weather conditions in western Oklahoma and adjacent north Texas. Additionally, a weak low level thermal ridge extending northward along and just west of highway 81 will lend its support to fire weather conditions.
1035 PM CDT Fri Apr 5 2024 (This evening through Saturday) Fire weather, storms, and strong winds are all in the forecast for Saturday as an upper level low treks through the central plains. ***Fire Weather*** The aforementioned winds will combine with RH values in the low teens (and probably a few single digit RHs in our far western counties) to create critical to extreme fire weather conditions in western Oklahoma and adjacent north Texas. Additionally, a weak low level thermal ridge extending northward along and just west of highway 81 will lend its support to fire weather conditions.
417 AM EDT Sat Apr 6 2024 A stubborn low pressure system will continue to spin over New England through today with cold northwest flow and scattered rain and snow showers.
Meanwhile, an upper ridge axis will cross the Lower Mississippi River today, making its way into the Southeast States tonight. All in all, the prevalence of high pressure at both the surface and aloft will maintain a dry air mass and clear skies. High temperatures today will be similar or slightly cooler than yesterday, given the turn from westerly to northerly surface winds.
(Today) Clear skies and cool conditions prevailed across the area for the overnight, with air temperatures ranging from the lower 30s to mid 40s. The block was beginning to break down, as it's western upper low over the Great Basin breaks down, and another system south of the Gulf of Alaska moves towards the western states. The eastern low of the block was finally heading further off of the east coast, which should gradually end the recent cooler period. Thus expect partly cloudy skies today with highs in the lower to middle 60s.
(Today and tonight) The strongest core of upper level wind flow associated with a broad upper low across western CONUS is currently spread across the AZ/NM state line, steadily heading east toward our area. Surface westerlies will increase sharply behind a Pacific cold front progged to move across the NM/TX state line before sunrise and shift east across our CWA by early afternoon. Cooler air aloft eventually arrives tonight, dropping lows into the upper 30s/mid 40s area wide with breezy west winds persisting overnight.
1247 AM CDT Sat Apr 6 2024 (Tonight) No major changes needed to the ongoing forecast this Fri evening, as a large area of high pressure continues to build eastward into the Midwest/OH Valley states. The wind flow should diminish a bit more overnight, with lows falling into the mid 30s for most spots, except NE AL where lows may reach the lower 30s.
129 AM EDT Sat Apr 6 2024 (Rest of today through Saturday) Dry and comfortable weather conditions are expected through the short-term period across South Florida as an abundantly dry air mass settles in and high pressure build over the area. With mostly clear skies and light NW winds, tonight's lows will range from the low 50s around the interior/Lake Okeechobee region, to the upper 50s to low 60s along the coast.
321 AM EDT Sat Apr 6 2024 The pattern aloft early this morning has a low exiting the New England coast with ridging building to our west over the Gulf of Mexico. At the surface, troughing to the northeast extends south over part of the state as high pressure sits over the eastern Gulf. This setup will favor similar conditions today as yesterday, albeit slightly warmer.
352 AM EDT Sat Apr 6 2024 Slightly cool weather caused by high pressure to the north persist over the weekend.
With the flow coming across the moist and relatively warmer gulf during the first half of this night, and temperatures over land radiationally cooling, this development makes sense. Once the trough moves south, which will change the winds from west/southwest to north, this fog will move south of the area.
1201 AM EDT Sat Apr 6 2024 Low pressure in the Gulf of Maine will continue chances for rain and snow showers through Saturday.
For Today, high pressure will build from the north northwest through the day. High pressure ridge will be centered overhead Tonight, with light winds and radiational cooling taking temperatures down into the mid 40s away from area water ways and the coast.
336 AM EDT Sat Apr 6 2024 Isolated to scattered showers are expected today with low pressure lingering in the Gulf of Maine through tonight.
As the upper-level low moves through the Great Basin area, a quick moving ridge slides over NorCal Saturday morning, which will help clear skies in the Valley. This will keep things cooler this morning with the potential of frost across the Valley, mainly above 1000 feet.
1124 PM EDT Fri Apr 5 2024 Deep low pressure spinning away from New England will maintain breezy and cool conditions into Saturday with rain and snow showers that will diminish.
215 AM EDT Sat Apr 6 2024 Deep low pressure spinning away from New England will maintain breezy and cool conditions into Saturday with rain and snow showers that will diminish.
An upper level low will track east from the Rockies and into the central Plains by this evening. Expect highs today in the low to mid 80s. Cooler temperatures can be expected tonight, with lighter winds and overnight lows in the mid and upper 40s.
We will see plenty of sunshine today, and although it will be warmer than yesterday the high temperatures will still be some 5-10 degrees below seasonal normals. Some locations especially across the north may dip to or even slightly below freezing.
1205 AM CDT Sat Apr 6 2024 (The rest of tonight) Pressure gradient at the surface will tighten during the overnight hours in response to approaching low pressure. Strong negatively tilted upper trough will swing into the central Plains during the day Saturday. Still the potential for a few marginally severe storms during this time period given the low CAPE/high shear environment.
1156 PM CDT Fri Apr 5 2024 - Low temperatures will drop below freezing tonight.
1220 AM CDT Sat Apr 6 2024 - A Freeze Warning and Frost Advisory is in effect for the entire region from 12-8AM Saturday with temperatures falling into the low to mid 30s.
340 AM EDT Sat Apr 6 2024 A stubborn low pressure system will continue to spin over New England through today with cold northwest flow and scattered rain and snow showers.
1255 AM CDT Sat Apr 6 2024 - Temperatures at or below freezing tonight may pose a risk to sensitive vegetation across the area. 18z surface analysis showed a large area of high pressure stretching from Lake Superior toward the lower Mississippi River Valley, with a warm front in place from eastern Colorado into northern Texas. High pressure will be the primary driver of our weather over the next 24-36 hours, with continued dry and quiet conditions to start the weekend. our more widespread low-level CU today with drier air more prevalent in the low levels. Winds will be on the increase out of the southeast behind the high, with gusts during the afternoon around 20 MPH.
102 AM EDT Sat Apr 6 2024 Large closed low along the New England/Canadian maritimes will continue to churn very slowly over that area through Saturday.
This upper level trough will move to western Nebraska by late this afternoon. Although not a WAA wind, the strong winds will provide for good mixing under upper level ridging which will allow highs to rise into the 60 across the east and the low to mid 70s west.
135 AM EDT Sat Apr 6 2024 Low pressure will shift east of the region tonight with high pressure building over the area to start the weekend.
623 AM CDT Sat Apr 6 2024 Today through Tonight: The trough to ridge pattern will remain over the southern half of CONUS. Throughout the day broad surface ridging will continue to move eastward across our area, keeping the the start to the weekend dry and free of rain chances. Expect mostly clear skies for a majority of the day, with some increasing higher clouds,as northerly flow winds will shift southerly overnight ahead of a cold front. Daytime temps will be slightly warmer today with high temperatures ranging from the low 80s in the SW to the low 70s in the NE. Expect this trend to continue overnight as low temps warm a few degrees ranging from the low 60s in the west to the upper 40s in the east.
The highest combined impacts of snow and wind likely will be over Campbell County.
647 AM EDT Sat Apr 6 2024 High pressure will build into the area today and move off to the east on Sunday.
However, a weak cold front will intrude into the BRO CWFA on Sunday, which may generate some isolated convection over the northern half of the lower Texas coastal waters at that time. Temperature-wise, above normal daytime highs and overnight lows will occur, although values on Sunday will be a few degrees lower due to increased cloud cover and a more easterly to northeasterly flow courtesy of the cold front intrusion. Finally, due to elevated seas and increased winds along the Lower Texas Coast, there will be a High Risk of rip currents at the local beaches today until around sunset today.
A cold front will push toward the region Sunday with scattered to numerous showers and thunderstorms Sunday afternoon into Sunday night.
921 AM EDT Sat Apr 6 2024 High pressure will build into the area today and move off to the east on Sunday.
623 AM CDT Sat Apr 6 2024 (Today and tonight) The strongest core of upper level wind flow associated with a broad upper low across western CONUS is currently spread across the AZ/NM state line, steadily heading east toward our area. Surface westerlies will increase sharply behind a Pacific cold front progged to move across the NM/TX state line before sunrise and shift east across our CWA by early afternoon. Cooler air aloft eventually arrives tonight, dropping lows into the upper 30s/mid 40s area wide with breezy west winds persisting overnight.
Temperatures will climb well into the 50s to low 60s as H5 ridging traverses the area. An upper low is approaching from the southwest, which is serving to amplify the pattern such that we will see increased pressure gradients through at least mid-afternoon to early evening. As the low approaches the area tonight, rain chances increase, especially along and south of Highway 2.
Surface winds will become breezy through the day today as we become sandwiched between an approaching cold front and an exiting high pressure system. Temperatures for Sunday will reach into the low 80s in land and into the upper 70s along the coast.
(Rest of Today) Mostly sunny early morning skies have allowed for temperatures to recover into the low 40s across the area. An omega block at both surface and mid levels will begin to deteriorate today leaving us with one more day under the influence of high pressure to the north. This will keep winds light and allow temperatures to rebound from the late week cool down into the low to mid 60s this afternoon.
This upper level trough will move to western Nebraska by late this afternoon. Although not a WAA wind, the strong winds will provide for good mixing under upper level ridging which will allow highs to rise into the 60 across the east and the low to mid 70s west. Showers will be possible across northern Missouri nearest the vicinity of the low.
705 AM EDT Sat Apr 6 2024 (Today through Sunday) Excellent weather is expected this weekend across South Florida as high pressure builds over the area and a very dry airmass remains in place. High temperatures will be in the low 80s on both days, with tonight's lows ranging from the mid 50s around the interior/Lake O region, to the low to mid 60s along the coast.
Snow levels will be quickly rising, and minimal impacts are expected over the highest passes above 3000 feet. After the departure of the trough, an expansive Pacific ridge will begin building in.
A Wind Advisory may become necessary but, for now, wind gusts this high are not anticipated to become widespread.
Rain and snow showers will taper off early Saturday morning, a dry and slightly warmer weekend is expected, with less wind.
Temperatures along the Island Chain are in the lower to mid 70s with dew points in the lower to mid 50s making it feel quite comfortable to be outside. Elongated high pressure has set up over the Eastern United States extending south through the Florida Peninsula and into the Keys.
1023 AM EDT Sat Apr 6 2024 Isolated to scattered showers are expected today with low pressure lingering in the Gulf of Maine through tonight. Conditions become drier Sunday as high pressure builds across the North Country.
Main concern today will be the low afternoon dewpoints producing dry conditions area-wide. Frost advisory is likely over much of the area tonight with the possibility of freezing warning for southwest Virginia, northeast Tennessee, and southwest North Carolina. We will see plenty of sunshine today, and although it will be warmer than yesterday the high temperatures will still be some 5-10 degrees below seasonal normals. Some locations especially across the north may dip to or even slightly below freezing.

Hope your plants are covered up! Today is looking fabulous with ample sunshine and highs warming into the low to mid 60s as a ridge builds in from the west. Temps will generally be in the low 40s except for out along the Plateau. A progressive upper-air pattern will take hold Sunday as a trough moves in, bringing a chance for rain and maybe some thunder Sunday evening. A trough moving across the Texas Panhandle will steadily work its way towards the southeast through the week.
859 AM EDT Sat Apr 6 2024 Slightly cooler weather caused by high pressure to the north persists over the weekend.
Wet weather will return late tonight into Sunday AM as a deep upper low tracks into the Central Plains and attendant downstream 850-700mb warm air advection forces numerous showers and isolated storms through the region from SW to NE; chances for measurable rain remain high (80-100%). Isolated storms could redevelop in a narrow corridor of SBCAPE, extending from SE to NW along/south of a warm front and ahead of an occluded front pushing in from the southwest.
A dry, reinforcing cold front will move southward across the peninsula today, causing winds to become northerly. Due to the sea breeze, some areas along the immediate coast may remain in the low 70s, especially north of the Cape.
Otherwise, plenty of sunshine today with afternoon highs generally in the low 80s. (Today through Sunday) Excellent weather is expected this weekend across South Florida as high pressure builds over the area and a very dry airmass remains in place. High temperatures will be in the low 80s on both days, with tonight's lows ranging from the mid 50s around the interior/Lake O region, to the low to mid 60s along the coast.
The upper low that brought a reminder of winter to Central California with snow, rain, thunder, hail, gust winds, and well below normal temperatures will continue to move off into the Great Basin today leaving a weak induced ridge for the region today aiding in the slow warming trend with temperatures getting to a level of only 10 degrees below normal for high temperatures after an early morning start with lows in the mid 30s to low 40s for the San Joaquin Valley floor.
617 AM CDT Sat Apr 6 2024 (Today through Sunday) Ridging build in across the region today leading to clearing skies. Winds shift more southerly on Sunday, with warm air advection kicking in ahead of an approaching trough. Looks like any rain chances associated with the approaching trough remain to our northwest through at least the early evening hours Sunday.
417 AM CDT Sat Apr 6 2024 Today through Tonight: The trough to ridge pattern will remain over the southern half of CONUS. Throughout the day broad surface ridging will continue to move eastward across our area, keeping the the start to the weekend dry and free of rain chances. Expect mostly clear skies for a majority of the day, with some increasing higher clouds,as northerly flow winds will shift southerly overnight ahead of a cold front. Daytime temps will be slightly warmer today with high temperatures ranging from the low 80s in the SW to the low 70s in the NE. Expect this trend to continue overnight as low temps warm a few degrees ranging from the low 60s in the west to the upper 40s in the east.
627 AM CDT Sat Apr 6 2024 (Today) Clear skies and cool conditions prevailed across the area for the overnight, with air temperatures ranging from the lower 30s to mid 40s. The block was beginning to break down, as it's western upper low over the Great Basin breaks down, and another system south of the Gulf of Alaska moves towards the western states. The eastern low of the block was finally heading further off of the east coast, which should gradually end the recent cooler period. Thus expect partly cloudy skies today with highs in the lower to middle 60s.
A cold front will push toward the region Sunday with scattered to numerous showers and thunderstorms during the afternoon and evening hours.
303 PM EDT Sat Apr 6 2024 High pressure will allow for dry conditions tonight.
Light snow will continue to favor the higher elevations of SW Idaho today as the center of the low pressure system in SW Idaho moves slowly eastward.
159 PM EDT Sat Apr 6 2024 High pressure will build into the area today and move off to the east on Sunday.
1235 PM EDT Sat Apr 6 2024 Slightly cooler weather caused by high pressure to the north persists over the weekend.
As of right now, the HRRR is BY FAR the outlier, but here's what I'll say: if we're able to realize 300-500 J/Kg, shear values are healthy enough to minimally open the door for a the low-end severe weather threat west of I-65 -- and I mean our counties touching the TN River.
237 PM EDT Sat Apr 6 2024 Upper low off of the New England coast will move further offshore into the Atlantic tonight.
125 PM PDT Sat Apr 6 2024 Weak high pressure building over California will bring sunny to partly cloudy skies and lighter winds this weekend.
(This evening through Sunday night) For tonight and Sunday, the overall trend will be for slowly diminishing winds as the vigorous upper level low pressure system moves northeast into western Nebraska early this evening, then further east into northwestern Iowa and southeastern South Dakota by late Sunday afternoon.
128 PM EDT Sat Apr 6 2024 Isolated to scattered showers are expected today with low pressure lingering in the Gulf of Maine through tonight. Conditions become drier Sunday as high pressure builds across the North Country.
Discussion: For tonight, surface ridging will remain across the southern Appalachians with strengthening ridge aloft. Freezing conditions expected across much of southwest Virginia, northeast Tennessee, and southwest North Carolina.
Snow showers continue today and tomorrow as the low moves eastward and an upper level trough drops down into our area to take its place.
209 PM CDT Sat Apr 6 2024 Today through Tonight: The trough to ridge pattern will remain over the southern half of CONUS. Throughout the day broad surface ridging will continue to move eastward across our area, keeping the the start to the weekend dry and free of rain chances. Expect mostly clear skies for a majority of the day, with some increasing higher clouds,as northerly flow winds will shift southerly overnight ahead of a cold front. Daytime temps will be slightly warmer today with high temperatures ranging from the low 80s in the SW to the low 70s in the NE. Expect this trend to continue overnight as low temps warm a few degrees ranging from the low 60s in the west to the upper 40s in the east.
Temperatures along the Island Chain are currently in the mid to upper 70s with a few locations reaching the lower 80s such as the Big Pine Key RAWS coming in with 82 degrees this afternoon. Elongated high pressure with an extension of this high south down the Florida Peninsula and into the Keys is causing west to northwest breezes of near 10 knots with Carysfort actually observing southwest to west winds due to the heating of South Florida as a thermal low or lower pressure developed over the mainland. The main theme for the next several days will continue to be high pressure dominating the pattern.
Still looking for thunderstorm development late this afternoon/earlyevening in the vicinity of a dry line/pacific cold front as it moves into eastern Oklahoma. Some of the storms could become strong to severe in this high shear/low CAPE environment mainly across northeast Oklahoma.
(This evening through Sunday) Considerable high cloudiness was drifting overhead of an upper ridge west of the area.
Closed areas of lower heights embedded within, and rotating through, an upper level trof, usher in a spring storm favoring widespread precipitation across the region.
358 PM EDT Sat Apr 6 2024 Low pressure off the New England coast will continue to provide cloudy skies and isolated to scattered rain and snow showers through tonight.
