418 AM EDT Thu Apr 1 2021 A cold front will continue moving through central NC this morning, with high pressure building into the area from the west thereafter. The high will remain over the region through the weekend. A cold front will continue moving through central NC this morning, with cold high pressure slowly building into the region in its wake. The strong pressure gradient between the departing trough and incoming high will result in strong, gusty northwest winds through tonight, though gusts should gradually decrease this evening.
Northwest flow aloft was currently bringing in a Canadian air mass and with a clear sky and light wind, temperatures were already in the low to mid 30s. Areas of the eastern Ozarks will again see lows in the mid 20s on Friday morning with slightly warmer temperatures in the mid 30s over the western CWA. The western CWA will be getting a frost advisory with temperatures at or slightly above freezing. Friday will begin the warm up phase and we'll have some upper level ridging moving into the area and an increase in southerly surface winds.
With moist soils and vegetation from recent rains, dewpoints near or below freezing, and overnight lows in the mid 30s, areas of frost are possible tonight, especially for areas south of Interstate 30. Under the influence of cool high pressure, afternoon high temperatures will only climb into the low to mid 60s. Otherwise, dry conditions to continue into Thursday night with temperatures forecast to fall into the low to mid 30s.
GKS The warming trend will continue through the weekend into the next work week due to upper level ridging over the Plains and Central US, and persistent south-southwest winds.
226 AM MDT Thu Apr 1 2021 Current surface map places high pressure from the central plains into the western Great Lakes. Flat upper ridge sets up across the area through the weekend with a few embedded impulses crossing the northern plains.
It will not be quite as cold Thursday morning with lows mainly in the lower 40s.
Synoptically, a broad area of low pressure moving into the Northeast will push the aforementioned front out of our area by this afternoon and into Friday. Behind it, a high pressure ridge will begin to build over the region and will stay in place during this period. As a result, cooler and dry conditions will settle into the area starting Friday morning with temperatures dropping over 10 degrees compared to this morning.
A large upper ridge will move into the Rockies and central CONUS Friday and into the weekend with a warming trend.
Much warmer and drier conditions return for the weekend. Lake enhanced snow showers already well underway as expected given passage of secondary cold front and embedded vort max within broader midlevel trough. 00Z KGRB sounding measured -12C at 850mb and did not even sample core of thermal trough headed for our area later this morning. Of bigger concern at this point is theta-e profiles indicate a very unstable environment in the lowest 3km that extends well inland. Highs today will remain stuck in the mid 30s thanks to potent (near record for KDTX 850mb temp climatology) thermal trough. Ideal radiational cooling with clear skies and calm winds will lead to an even colder night despite departure of best thermal trough aloft.
Sfc pressure gradient will tighten today as lee side trough develops over Alberta into Montana. Friday will see warmer temperatures as highs climb into the mid 50s west to mid 60s west but winds look a bit less (15-25 mph) and dew point temps look higher and therefore RH values lower into the 30-35 pct range for most. Upper-level ridging will be the predominant feature of this forecast.
A warming trend is on tap to continue through the weekend as high pressure builds over the region.
The upper level trough is moving eastward through the Tennessee Valley early this morning, with a strong cold front now southeast of Central Alabama. This will keep frost development limited to sheltered locations across the north, despite the cooler temperatures. Temperatures around sunrise will be in the low to mid 30s north to lower 40s south. Strong cold advection and a tightened pressure gradient will lead to cooler and breezy conditions today. High pressure will move southeastward overnight, becoming centered over western TN Friday.
Today Through Friday Night A strong area of high pressure at both the surface and upper levels will bring quiet weather conditions to Arkansas through the short term. Ample sunshine will be noted today however northerly winds will help keep temperatures in check with highs only reaching the lower 50s over northeast AR to lower 60s over southwest Arkansas.
A broad upper trough has moved off to the east and ridging is slowly building across the region.
Temperatures have quickly cooled this evening behind the cold front with low/mid 40's across the region as of 930 PM and mid/upper 30's in the higher elevations. N to NW winds become gusty at all sites early Thursday around 14Z as high pressure builds in from the northwest.
Clear skies will again allow for good radiational cooling, with the coldest temperatures focused across central and eastern Missouri where overnight lows will once again drop to below freezing. Southerly flow on the backside of the high should keep temperatures near to slightly above freezing across eastern Kansas and far western Missouri. As such have issued a Freeze Warning for central Missouri forecast counties along and south of the Missouri River where temperatures are most likely to fall below freezing and vegetation is most susceptible. A Frost Advisory has also been issued just west of the Freeze Warning where temperatures are expected to fall to near, or just below freezing.
With dewpoints in the 20s and lower 30s, this will equate to afternoon humidity values below 20 percent for the western half of the area and in the lower 20 percent range to the east. Dry weather will continue into Friday with highs slightly warmer, topping out in the middle 60s to lower 70s.
An upper level trough extends from the Great Lakes southward into the Tennessee Valley with the cold front now to the south and east of the area. Temperatures this morning will start out in the low to mid 30s for most locations and will only climb into the upper 40s to low 50s for highs. The warmest guidance suggests that temperatures will be below freezing for the entire forecast area on Friday morning. However, northerly winds in the low-levels will keep temperatures on the cold side with highs only climbing into the low to mid 50s.
Eventually they will predominate from the south by this evening as the high slides off to the east of the region. Although the clear skies will continue overnight into friday morning, the radiational cooling will be slightly offset by southerly winds advecting in warmer conditions. The area of high pressure that slides across the region today will be centered over the Ohio River Valley. A tight pressure gradient will develop ahead of an approaching cold front that will move into the Dakotas and Nebraska. These south winds will also help to bring in warmer air with highs reaching the 50s by Friday.
A warming trend is on tap to continue through the weekend as high pressure builds over the region. High pressure will continue to build through the week bringing a warming trend that will continue through the weekend. There is a closed low that is approaching the southern CA coast that will spread some mid level moisture across the region this afternoon and evening.
Dry weather pattern continues with the upper level pattern transitioning to a broad western ridge setting up and expanding into the area. The ridge flattens into Friday which will help a lee trough deepen and in turn winds increase from the south with increasing moisture advection into the area. Again, a broad ridge appears to be reinforced day after day through the weekend. With time, the next Pacific trough deepens and digs into the SoCal region which will allow for a southwest flow regime to develop.
322 AM CDT Thu Apr 1 2021 Quiet and warmer weather is expected today and tonight. Upper level high pressure west of the area this morning will shift overhead tonight. RMcQueen The upper low currently situated just off the southern California coast will weaken to an open wave trough over the Four Corners region by tomorrow afternoon.
Dry and nearly clear skies will allow some strong warming, while the high pressure that brings the clear skies also keeps winds fairly light.
The clouds are a product of moisture/saturation at the top of a well mixed boundary layer that exists within deep upper level trough. The deep upper level trough slowly traverses the region today maintaining this cold airmass overhead. With the upper level trough beginning to move east, height rises work into SE MI by mid to late morning further decreasing the depth of moisture with saturation occuring around/below 4000ft. Another cold night is in store tonight as skies clear dropping lows into the low 20s to upper teens. Ridging develops over the central US Friday and slowly moves east toward the Great Lakes.
654 AM CDT Thu Apr 1 2021 Ideal radiational cooling conditions have developed overnight with dry high pressure centered over the Upper Midwest. Temperatures will be slow to moderate today however, as the warmest air under the building ridge remains over the plains states. The upper level ridge continues to build into Friday which will bring a return to above normal temepratures, as highs warm into the upper 50s to mid 60s.
518 AM MDT Thu Apr 1 2021 The large ridge of high pressure continues to exert its influence across our area this morning with nary a cloud in sight. Upper level flow under this ridge continues to be from the south which will cause a marked warm-up over the coming days. The only concern in the short term period is a very weak area of low pressure that's currently off the Southern Cali coast. The low will continue to weaken as it moves across the Great Basin though some minimal moisture does look to advect into souther portions of the CWA. By Friday night, the weak system exits the region allowing the ridge to reach it's full potential over the weekend. Under this ridge temperatures will continue to rise with highs nudging 80 degrees, and low-to-mid 60's for mountain towns.
Temperatures tonight will remain cool with areas across southwest Nebraska falling to below freezing with temperatures in the low 30s. Upper level ridge continues to build across the western CONUS moving into the High Plains this weekend, become more of a broad ridge as it moves into the region. The lowest humidity (below 15% in spots) will primarily occur in the panhandle, while the strongest winds (gusts 35+ mph) will be concentrated in the northern Sandhills.
Currently, upper level ridge building into the high plains region, with mid level WAA spreading east into the western Dakotas early this morning.
High pressure will push temperatures well above normal through the upcoming weekend.
Expect much warmer conditions than on Thursday morning, with temperatures remaining above freezing for most. A strong upper-level ridge helps bring even warmer conditions on Friday, with highs rising to the mid 60s east of I-29, and surging into the mid to upper 70s along and west of the James River Valley in South Dakota.
828 AM EDT Thu Apr 1 2021 A cold front will bring snow to NY and PA early this morning, then push scattered lake effect snow showers into Upstate NY Thursday afternoon.
High pressure will move towards the region today and northerly winds will ensue this afternoon. Today Through Friday Night A strong area of high pressure at both the surface and upper levels will bring quiet weather conditions to Arkansas through the short term. Ample sunshine will be noted today however northerly winds will help keep temperatures in check with highs only reaching the lower 50s over northeast AR to lower 60s over southwest Arkansas.
635 AM EDT Thu Apr 1 2021 A cold front will bring snow to NY and PA early this morning, then push scattered lake effect snow showers into Upstate NY Thursday afternoon.
344 AM MDT Thu Apr 1 2021 The large ridge of high pressure continues to exert its influence across our area this morning with nary a cloud in sight. Upper level flow under this ridge continues to be from the south which will cause a marked warm-up over the coming days. The only concern in the short term period is a very weak area of low pressure that's currently off the Southern Cali coast. The low will continue to weaken as it moves across the Great Basin though some minimal moisture does look to advect into souther portions of the CWA. By Friday night, the weak system exits the region allowing the ridge to reach it's full potential over the weekend. Under this ridge temperatures will continue to rise with highs nudging 80 degrees, and low-to-mid 60's for mountain towns.
925 AM CDT Thu Apr 1 2021 Northerly winds helped keep temperatures up a few degrees more than the models forecast this morning, but we did start out near freezing in many locations. The warmest guidance suggests that temperatures will be below freezing for the entire forecast area on Friday morning. However, northerly winds in the low-levels will keep temperatures on the cold side with highs only climbing into the low to mid 50s.
805 AM EDT Thu Apr 1 2021 A cold front is currently moving into the Nature Coast.
407 AM CDT Thu Apr 1 2021 Ideal radiational cooling conditions have developed overnight with dry high pressure centered over the Upper Midwest. Temperatures will be slow to moderate today however, as the warmest air under the building ridge remains over the plains states. The upper level ridge continues to build into Friday which will bring a return to above normal temepratures, as highs warm into the upper 50s to mid 60s.
Cooler, but still mild this weekend. Upper level ridge over NorCal will flatten a bit over the next few days, with dry conditions, light winds and much above normal temperatures continuing. A series of disturbances passing through the Pacific Northwest will gradually lower heights Friday into the weekend, cooling the temperatures back into the low 80's Friday then 70's Sat/Sun, but these readings are still 5 to 10 degrees above normal.
337 AM MDT Thu Apr 1 2021 Northeast Colorado will remain dry and mostly clear Thursday as the upper ridge continues to build. The warming trend will continue and temperatures should be around 10 F warmer than normal Thursday afternoon. Overnight lows are also expected at almost 10 F warmer than normal Thursday night, in 30s F on the plains and almost 40 F in the Denver metro. A Rex block off the east coast of North America will result in upper level ridging for much of the CONUS through this weekend. On Friday, a weak trough will undercut the ridge and track across the Southern Rockies. Ridging will persist over the Central Rockies through the weekend.
622 AM EDT Thu Apr 1 2021 A cold front will bring snow to NY and PA early this morning, then push scattered lake effect snow showers into Upstate NY Thursday afternoon.
Currently have an upper trough extending from the Great Lakes down into the Tennessee Valley, with upper ridging over the Great Basin. At the surface, high pressure is centered over eastern Nebraska and extends down into central TX. Broad area of upper ridging is expected over the central and northern Plains for the weekend which will continue to promote above normal temperatures. Both the GFS and ECMWF close off the upper low and track it east on the Tue night-Wed.
Another pleasant day on tap for the Mid-South with highs in the lower 50s. This should allow winds to relax a bit and temperatures to plummet to or near freezing by sunrise across a large portion of the Mid-South.
This pattern is largely due to an offshore area of high pressure exerting its influence over the area. We will be under the influence of this high pressure system over the next few days, however the influx of clouds will help keep morning lows a little milder while afternoon highs will be somewhat cooler.
Issued by National Weather Service Lincoln IL 910 AM CDT Thu Apr 1 2021 Abundant sunshine in place this morning as the center of the high edges closer to the region. Highs still on track to largely reach the mid 40s, a bit warmer along the Missouri River valley toward central Missouri. GKS The warming trend will continue through the weekend into the next work week due to upper level ridging over the Plains and Central US, and persistent south-southwest winds.
317 AM MDT Thu Apr 1 2021 A ridge pattern continues for the next few days causing dry weather and above-normal temperatures across the region.
Thermal ridge builds over southern Montana underneath the flattening ridge and this will allow temperatures to rise into the upper 60s to lower 70s. A strong ridge will dominate the the weather, bringing warming downslope flow with it.
545 AM MDT Thu Apr 1 2021 A ridge pattern continues for the next few days causing dry weather and above-normal temperatures across the region.
Moving on to temperature issues, this morning has been fairly chilly however tonight and tomorrow's lows are near freezing for a few northern locations.
A warming trend is on tap to continue through the weekend as high pressure builds over the region. Weak low pressure off the California coast will stream increasing mid and high clouds across the region later today and through this evening before shifting east overnight. High pressure will continue to build through the week bringing a warming trend that will continue through the weekend. There is a closed low that is approaching the southern CA coast that will spread some mid level moisture across the region this afternoon and evening.
435 AM MDT Thu Apr 1 2021 Current surface map places high pressure from the central plains into the western Great Lakes. Flat upper ridge sets up across the area through the weekend with a few embedded impulses crossing the northern plains.
Weak surface lee trough will result in occasional swly wind gusts to 30-35kts along the central mt chain, northeast and east central NM. A quick- hitting storm system arrives on Friday, bringing virga and dry thunderstorms to the high terrain and increased cloud cover elsewhere.
Currently a ridge of high pressure is propagating eastward over the region. The axis of the high pressure looks to move over the area during the afternoon. Given the main synoptic influence over the area is the ridge, clear skies and warm weather are expected throughout this afternoon across the CWA. Highs today should warm to slightly above average values, with mid 60s/low 70s over the eastern plains, the low 60s in the San Luis Valley, and mid 40s/mid 50s for higher elevations. Heading into tonight, the ridge will continue moving eastward, with a small upper level disturbance expected to begin influencing the area, but it will remain just to the south our CWA. Temperatures during this period should fall into the low 40s/upper 30s for the eastern plains, mid 20s/low 30s for the San Luis Valley, and the 20s for higher elevations.
/issued 255 AM CDT Thu Apr 1 2021/ A cool dry airmass continues to filter into the region in the wake of the cold front that is now well offshore. Gusty winds currently will gradually relax through the day as high pressure settles in over the region.
A weak low pressure system could bring some virga or sprinkles this afternoon with a slight chance of thunderstorms in the mountains.
Much colder and drier air continues to flow into the region during the period in the wake of a cold front. Dry conditions continue through Friday as a large dome of cool high pressure builds into the eastern states. Lows tonight range from the lower 30s inland to the mid/upper 30s at the coast, and a Freeze Warning is now in effect for interior areas late tonight into early Friday morning for overnight lows potentially reaching 30 degrees. Highs on Friday will be slightly warmer than today and range from the upper 50s well inland to the lower 60s elsewhere.
615 AM CDT Thu Apr 1 2021 Upper level high pressure ridge west of the area will approach and pass overhead tonight. /issued 322 AM CDT Thu Apr 1 2021/ Quiet and warmer weather is expected today and tonight. Upper level high pressure west of the area this morning will shift overhead tonight. RMcQueen The upper low currently situated just off the southern California coast will weaken to an open wave trough over the Four Corners region by tomorrow afternoon.
Increasing clouds and cooler conditions expected to close out the week as high pressure exits western Washington to the east.
As the ridge of warm temperatures and high pressure moves into our region from the west beginning today, fire weather concerns are elevated today. This weather pattern of the broad warm ridge of high pressure to our south will persist through this weekend.
Issued by National Weather Service Lincoln IL 1251 PM CDT Thu Apr 1 2021 Abundant sunshine in place this morning as the center of the high edges closer to the region. Highs still on track to largely reach the mid 40s, a bit warmer along the Missouri River valley toward central Missouri. GKS The warming trend will continue through the weekend into the next work week due to upper level ridging over the Plains and Central US, and persistent south-southwest winds.
258 PM CDT Thu Apr 1 2021 High pressure is centered over the middle Missouri River Valley this afternoon and will slowly shift east across the Midwest through the weekend.
1139 AM MDT Thu Apr 1 2021 The large ridge of high pressure continues to exert its influence across our area this morning with nary a cloud in sight. Upper level flow under this ridge continues to be from the south which will cause a marked warm-up over the coming days. The only concern in the short term period is a very weak area of low pressure that's currently off the Southern Cali coast. The low will continue to weaken as it moves across the Great Basin though some minimal moisture does look to advect into souther portions of the CWA. By Friday night, the weak system exits the region allowing the ridge to reach it's full potential over the weekend. Under this ridge temperatures will continue to rise with highs nudging 80 degrees, and low-to-mid 60's for mountain towns.
Models show only modest warming at 850 mb Friday versus Thursday (net increase about +2C), allowing for afternoon temperatures in the lower 70s.
1211 PM CDT Thu Apr 1 2021 Ideal radiational cooling conditions have developed overnight with dry high pressure centered over the Upper Midwest. Temperatures will be slow to moderate today however, as the warmest air under the building ridge remains over the plains states. The upper level ridge continues to build into Friday which will bring a return to above normal temepratures, as highs warm into the upper 50s to mid 60s.
A broad slow moving anticyclone across the e-se CONUS with ridging extending wwd into W TX and the weak flow aloft will favor the aforementioned se winds and Fri across the PB winds of 20-30 mph are likely. SE winds will eventually return low-level mstr wwd by Sat PM, but not very good timing for with the passage of a weak mid-level shrtwv trof. Although it will be a few degrees warmer Sun the se winds will persist with low-level mstr farther w into SE NM. Of course alot can change between now and then, but ECMWF/CMC/GFS are all in pretty agreement that concerns will be increasing and will eventually depend on the timing of the passage of a mid-latitude cyclone to the n.
144 PM CDT Thu Apr 1 2021 High pressure building into the Tennessee Valley is leading to clear, sunny skies today, however the northerly winds on the leading edge of the High is helping to keep temperatures cool. After a cold start Friday morning, temperatures should get up into the low-to-mid 50s Friday afternoon.
/This Afternoon/ The mid-morning sfc analysis indicates Canadian sfc ridging anchored from the Midwest S into the Srn Plains, which will maintain the abnormally cool and dry air mass in place areawide for the afternoon. The result will be very low RH's and pleasant temps in the lower to mid 60s, which is mostly reflected in the ongoing forecast.
