1034 AM EST Sun Feb 20 2022 Currently - Breezy and somewhat cooler conditions this morning are being driven by a recent cold front passage. Winds are already out of the northeast and has limited the amount of cooling, resulting in temperatures in the lower to mid 70s with dew points in the mid to upper 60s. Short Term Update - The high pressure responsible for our breezy conditions continues to drive eastward off the mid Atlantic coast. Moderate to fresh northeasterly breezes are being driven by high pressure centered over the mid Atlantic Coast. Winds will continue to relax a bit more through the afternoon as the high slides further into the Atlantic and South Florida gets some sunshine.
High pressure to the northeast of the regional terminals will promote east to northeast winds this afternoon 10-12 knots at the coastal sites and KJAX with 8-10 knots at at KVQQ and KGNV as some low level clouds around 5. 0 kft and 5-8 knots inland with mostly sunny skies as high pressure to the northeast skirts further eastward away from the region. Conditions will become warmer today as high pressure begins to build more towards the east and northeast. Overnight low temperatures will drop into the 40s and 50s, with warmer temperatures occuring further to the south.
Forecast - Over the next several days, the previously mentioned high will push further out to sea while maintaining a ridge across the southeastern United States and across the Gulf of Mexico. Thereafter, building deep layered ridging should shut down shower potential. By mid week the upper level ridging will have strengthened. The ridge axis across the southeast will shift southeastward and extend almost east/west across northern Florida. The next mid latitude trough and associated cold front will begin advancing into the southeastern United States and northwestern Gulf of Mexico late this week. In response the ridge that was anchored across Florida will slip further southeastward then retreat out to sea.
351 PM EST Sun Feb 20 2022 High pressure will slide offshore tonight into Monday. High pressure will slide offshore tonight with light ely to calm winds and mainly clear skies. High pressure will be centered offshore while continuing to ridge into the area. Dry and increasingly warmer weather will build across Eastern North Carolina early to mid week. Rain chances will increase by the end of the week, with cooler weather for the first half of the upcoming weekend.
Surface analysis late this morning places a 1030 mb ridge of high pressure over the Southeast United States. As of 10 AM CST, southerly winds are advecting warmer air into the region with temperatures already in the 50s across many locations. Overnight temperatures will also be warmer with mid to upper 40s expected. Strong WWA, PWAT values still in the 99% of climatology, a LLJ expected to strengthen, as well as CAPE values around 700-1000 J/kg range and moderate shear coupled with a cold front moving in from the northwest severe weather is now on the table.
1037 AM CST Sun Feb 20 2022 Windy and much warmer conditions will be observed across central Illinois today. Afternoon high temperatures will soar into the lower to middle 50s along and south of the I-70 corridor. 09z/3am surface analysis shows a sprawling ridge of high pressure extending from Quebec to the Gulf Coast. while low pressure develops over the Northern Plains.
148 PM EST Sun Feb 20 2022 High pressure remains in control again today with seasonably cooler temperatures, drier air and clear skies.
1204 PM EST Sun Feb 20 2022 Windy conditions are expected this afternoon as much warmer air returns from the southwest.
145 PM CST Sun Feb 20 2022 Warmer, sunny, and a bit breezy conditions continue today.
A Dry And Warmer Week Ahead. Onshore flow will moderate temps tonight along the coast, expecting temps to settle in the low 60s, while dropping into the upper 50s west of I-95. High pressure over the Mid-Atlantic slides to the western Atlantic, though we maintain dry conditions and easterly flow across Florida. A bit warmer tomorrow, afternoon highs reach the upper 70s along the coast and low 80s inland.
/AJ/ As the trough deepens over the desert southwest, the flow remains southwesterly aloft, ejecting a series of small waves through the region. The first of which is the low moving into the Midwest and dragging dragging a front into the region tomorrow night. Increasing southerly flow with a tightening pressure gradient will pull warmer temps/more moisture/increasing instability overnight.
204 PM MST Sun Feb 20 2022 Most recent surface analysis shows the low pressure system about to affect the region sitting over south central Montana, with a warm front across northwestern SD causing some weak radar returns. At the upper levels, quasi-zonal flow sits over the northern plains, expected to become more southwest as upper troughing digs into the western CONUS early this week.
539 PM CST Sun Feb 20 2022 The very warm weather we've had today will quickly be just a nice memory by Monday as a strong cold front races south across the region.
542 PM CST Sun Feb 20 2022 (This evening through Monday) It will be more mild tonight, with lows in the lower to mid 50s, as a lee trough brings occasionally gusty south winds and high clouds increase with approach of an upper level disturbance. Monday afternoon, temperatures warm up to highs in the lower to mid 80s Monday.
Also, expect LLWS over the higher terrain of the Ozarks (i.
111 PM PST Sun Feb 20 2022 Cooler and more unsettled weather returns by Monday.
545 PM CST Sun Feb 20 2022 Main challenge remains timing of the Arctic cold front Monday afternoon and then precip chances/type just behind the frontal passage Monday night. While character of the moistening within the low and mid-levels does not appear coherently deep, there is support for some very light precip developing just behind the front across the Flint Hills and southeast Kansas where thermal profiles could support either rain/drizzle or perhaps a period of freezing/frozen precip.
This could create areas of very low visibility, especially given the higher snow rates we could see.
947 PM EST Sun Feb 20 2022 High pressure will slide offshore tonight into Monday. High pressure will slide offshore tonight with light ely to calm winds and mainly clear skies. High pressure will be centered offshore while continuing to ridge into the area. Dry and increasingly warmer weather will build across Eastern North Carolina early to mid week. Rain chances will increase by the end of the week, with cooler weather for the first half of the upcoming weekend.
246 PM MST Sun Feb 20 2022 Snow chances remain in our area through midday Monday for our northern zones and Monday night for our southern zones as an upper level trough slowly moves through.
WAA has been on the increase and hence the temperatures having leveled off in the lower 60s to mid 60s. Dewpoints will continue to creep up and the warm front looks to be moving into the coastal areas now with backed easterly winds and lowering clouds across SETX.
630 PM EST Sun Feb 20 2022 High pressure will slide offshore tonight into Monday. High pressure will slide offshore tonight with light ely to calm winds and mainly clear skies. High pressure will be centered offshore while continuing to ridge into the area. Dry and increasingly warmer weather will build across Eastern North Carolina early to mid week. Rain chances will increase by the end of the week, with cooler weather for the first half of the upcoming weekend.
On Monday first wave of energy will eject out of the western trough. With northeasterly flow both terrain and temperatures cold enough for lake enhancement will play a role in increasing the snowfall across the highlands of Marquette,Baraga, Ontonagon and Gogebic County.
Surface analysis this afternoon places a ridge of high pressure over the Carolinas with southerly flow on the back side of high pressure present over the Lower Mississippi Valley. Clouds will begin to increase across the Mid-South tonight as the Lower Mississippi Valley transitions to southwest flow aloft and higher dewpoints begin to advect into the region.
350 PM CST Sun Feb 20 2022 The very warm weather we've had today will quickly be just a nice memory by Monday as a strong cold front races south across the region.
928 PM EST Sun Feb 20 2022 Atlantic high pressure will lead to unseasonably warm temperatures until a mostly dry cold front moves through late in the week. Rest of Tonight: High pressure centered over the Delmarva Peninsula will slowly shift eastward while a coastal trough attempts to form along the SC/GA coastline. Some weak radar returns have begun to appear over the offshore waters associated with the forming coastal trough.
448 PM MST Sun Feb 20 2022 Most recent surface analysis shows the low pressure system about to affect the region sitting over south central Montana, with a warm front across northwestern SD causing some weak radar returns. At the upper levels, quasi-zonal flow sits over the northern plains, expected to become more southwest as upper troughing digs into the western CONUS early this week.
Warmer, sunny, and a bit breezy conditions continue today.
The arctic cold front continues to push south and east this afternoon and through tonight. As the front pushes deeper into western Montana, warmer, moist air from the southwest will override the cold air near the surface. This situation will be conducive to snow in both the higher terrain and lower valleys. The position of the cold front and the depth of moisture remain wildcards for Monday morning, so there is a good chance for snow amounts to end up higher than the current numerical forecast indicates, especially for the Missoula and Mission Valleys. Wind chills in northwest Montana will get down to about 20 degrees below zero along the Highway 2 corridor east of Columbia Falls, while Polebridge could see wind chills of 30 below zero.
Clouds will gradually be on the increase, with return southerly flow advecting warmer and higher dew point air into the region.
A very light east to southeasterly surface flow will continue tonight along the western periphery of the ridge axis. Dewpoints will continue to increase into the mid to upper 50s over interior areas and in the lower 60s along the coast Monday night and conditions will become favorable for the development of patchy to areas of fog Monday night into Tuesday morning, especially closer to the coast. Lows Monday night will range in the upper 50s to lower 60s and highs Tuesday will range in the upper 70s to near 80 degrees inland and in the lower to mid 70s along the immediate coast.
Water vapor imagery indicates a developing west coast trough, and with that anticipate multiple upper waves ejecting from this feature into the region over the next couple days.
The ridge axis will extend across the FL peninsula keeping onshore flow the dominant regime today and tonight. Overnight, lows will also be above normal in the low to mid 60s.
- A high pressure will track in from the Arctic on Tuesday and remain impactful through the early weekend. The second wave will be driven by a deformation zone resulting from the encroaching low pressure center. For the most part, we are anticipating all snow with any freezing rain or drizzle lying just south of the MN/IA border and southeastward from Rochester. We are certain that the highest amounts will be where they set up, but uncertain in these exact locations. In general, the highest amounts will be in the a stretch across central Minnesota.
1231 AM EST Mon Feb 21 2022 High pressure will slide offshore tonight into Monday. High pressure will slide offshore tonight with light ely to calm winds and mainly clear skies. High pressure will be centered offshore while continuing to ridge into the area.
1136 PM CST Sun Feb 20 2022 Main challenge remains timing of the Arctic cold front Monday afternoon and then precip chances/type just behind the frontal passage Monday night. While character of the moistening within the low and mid-levels does not appear coherently deep, there is support for some very light precip developing just behind the front across the Flint Hills and southeast Kansas where thermal profiles could support either rain/drizzle or perhaps a period of freezing/frozen precip.
Low level thermal ridge downstream of wrn US troughing will build further on Monday. Theta- e ridge hung up down near the OH river and greatest low level moisture flux will pass well south of the cwa and which will keep rainfall amounts through Tue am limited to one half inch or less. Cold front in association with this sys will pass Tue night with robust cold advection following Wed.
On Monday first wave of energy will eject out of the western trough. With northeasterly flow both terrain and temperatures cold enough for lake enhancement will play a role in increasing the snowfall across the highlands of Marquette,Baraga, Ontonagon and Gogebic County. A stronger upper wave will eject out of the Plains on Tuesday with a more pronounced surface wave lifting into the lower Great Lakes. Once again continued northeasterly flow lake enhanced and upsloping will increase snow total across the higher terrain.
948 PM MST Sun Feb 20 2022 Most recent surface analysis shows the low pressure system about to affect the region sitting over south central Montana, with a warm front across northwestern SD causing some weak radar returns. At the upper levels, quasi-zonal flow sits over the northern plains, expected to become more southwest as upper troughing digs into the western CONUS early this week.
1132 PM CST Sun Feb 20 2022 The very warm weather we've had today will quickly be just a nice memory by Monday as a strong cold front races south across the region. Where as highs today in the upper 60s were around 25 degrees above normal, we'll see highs in the lower teens or around 30 degrees below normal by Tuesday. Monday will be the transition day with morning highs and then falling temperatures behind the cold front.
105 AM EST Mon Feb 21 2022 Atlantic high pressure will lead to unseasonably warm temperatures until a mostly dry cold front moves through late in the week. Some small and weak showers over the ocean associated with a coastal trough will continue to develop and lift north through the overnight. It'll be a warmer night compared to last night, with more cloud cover and an onshore flow.
334 AM EST Mon Feb 21 2022 High pressure will slide farther out to sea today into Tuesday morning.
1049 PM CST Sun Feb 20 2022 (This evening through Monday) It will be more mild tonight, with lows in the lower to mid 50s, as a lee trough brings occasionally gusty south winds and high clouds increase with approach of an upper level disturbance. Monday afternoon, temperatures warm up to highs in the lower to mid 80s Monday.
Look for a slight chance of a shower tonight with chances for showers and thunderstorms increasing tomorrow as moisture gets funneled south of a cold frontal boundary moving the the central plain states. The highs though look to make up into the lower 80s.
328 AM EST Mon Feb 21 2022 This afternoon in response to upper level troughing out west and upper level ridging expanding over the Gulf Coast our southwesterly flow aloft will deepen. At the surface a warm front will be shifted northward through the CWA. 28 A persistent subtropical ridge will bring very warm and potentially record-breaking temperatures during the first half of the forecast period. On the fringe of this ridge, persistent southwest flow will also set the potential for unsettled conditions and heavy rainfall for portions of far northwest Georgia as well.
Models depict broad high pressure dominating the area, keeping generally easterly winds in place for the short term.
Also, expect LLWS over the higher terrain of the Ozarks (i. An upper trough pattern will amplify and expand over the western CONUS over the next few days, with disturbances moving along the flow through the central and southern Plains. Strong, southerly flow will increase temps and moisture across the region ahead of the approaching trough and cold front. As increased heat and moisture collect ahead of the upper trough/disturbances and an approaching cold front, the region will destabilize Mon-Tues.

Temperatures vary quite a bit across the area with warmer temperatures where there are a little bit more wind and where the wind is near calm, the temperatures are a little cooler. A cold front is expected to move into the forecast area this morning and move through most of the area by mid day.
/Issued 328 AM EST Mon Feb 21 2022/ This afternoon in response to upper level troughing out west and upper level ridging expanding over the Gulf Coast our southwesterly flow aloft will deepen. At the surface a warm front will be shifted northward through the CWA. 28 A persistent subtropical ridge will bring very warm and potentially record-breaking temperatures during the first half of the forecast period. On the fringe of this ridge, persistent southwest flow will also set the potential for unsettled conditions and heavy rainfall for portions of far northwest Georgia as well.
Patchy morning fog will lift this morning with surface level onshore winds building in the afternoon as the high moves further to the northeast-east today. High temperatures today will reach up into the mid 70s and lower 80s for inland areas and in the lower 70s for areas along the coast.
A cold front was located just south of I-80 early this morning. Today, another mild day is in store, as a low pressure area approaches from the SW. This combination will take time to cool the north below freezing, but a continued threat in this convergent air will be fog development. By Midnight, east northeast winds in the far north will drop temperatures to the upper 20s to lower 30s, and a period of freezing drizzle should begin. Low pressure will ride up along the front by early Tuesday morning. Tuesday morning, as the low pulls east, a transition from rain/freezing rain to sleet and snow will occur, as the precipitation ends.
An amplifying upper level trough over the western U. Dry stable conditions under the ridging will support dry weather with ample sunshine and warming temperatures over the entire forecast area the remainder of today with temperatures climbing into the lower 80s over inland locations during the afternoon, with slightly cooler readings along the coast due to the sea breeze. Dry weather with even warmer temperatures (near record warmth) will be possible through the remainder of the week with high temperatures soaring into the mid to upper 80s over inland locations each afternoon, with overnight lows in the 60s.
Feel the highest accums from this banded snow event will in fact be just over the CWA line in far southern ND, but the radar loop over the past several hours shows enough moderate snow reflectivity over the far northern CWA where confidence is somewhat moderate to high that a handful of locations may still come in with 6+ inches by later this morning.
This inversion will mix well today and bring a very warm day as southwest winds develop ahead of a potent cold front, with near-record temperatures expected near Topeka.
A cold front is expected to slowly progress southeastward through the Mid-South.
304 AM CST Mon Feb 21 2022 A cold front was located just south of I-80 early this morning. Today, another mild day is in store, as a low pressure area approaches from the SW. This combination will take time to cool the north below freezing, but a continued threat in this convergent air will be fog development. By Midnight, east northeast winds in the far north will drop temperatures to the upper 20s to lower 30s, and a period of freezing drizzle should begin. Low pressure will ride up along the front by early Tuesday morning. Tuesday morning, as the low pulls east, a transition from rain/freezing rain to sleet and snow will occur, as the precipitation ends.
Temperatures are hovering in the lower to mid 70s, with dewpoints in the upper 60s to near 70, and winds on land from the northeast to east at 5 to 10 mph. Surface analysis depicts high pressure centered north of Bermuda and extending westward into the Southeastern states. Aloft, a deep layered ridge is centered over the southern Gulf of Mexico and the Yucatan Peninsula. Otherwise, warm and dry weather is in store for the next several days, as deep ridging builds overhead and dominates our weather pattern. Temps will be a few degrees above normal through the period, with highs in the lower 80s and lows in the lower 70s. The weather pattern will finally change during the weekend, as a longwave trough develops over the eastern CONUS and pushes a surface cold front down the Florida peninsula.
Winter weather has made a comeback to the Silver State as a cold front and associated snow moves through northern Nevada into central Nevada later this morning and afternoon.
with even warmer readings in the lower 60s noted south of I-70. Showers and a few thunderstorms will develop tonight into Tuesday ahead of a strong cold front that will bring a return to chilly winter weather for the middle and end of the week. Southerly winds will continue to transport warmer and increasingly moist air into the region today. Locations south of I-70 will see readings reach the lower 60s. As a cold front slowly approaches from the west, scattered showers will develop this evening. There may also be a window of opportunity for strong storms during the afternoon as several CAMs suggest a narrow line of convection forming immediately along the advancing cold front. As the cold front surges eastward, temps will drop during the afternoon.
Temperatures across our west and along the ridges continue to stay fairly mild in the upper 40s to near 50 under persistent southerly flow. Meanwhile, temperatures have dropped into the low 30s across some of our more sheltered eastern valleys, and have made some minor tweaks to temperatures based on recent trends. Meanwhile, low pressure will deepen over the central high plains with the support of an amplifying large scale upper trough over the western CONUS. This will be most pronounced in our western counties and ridges tonight, with much of the area still seeing valley temperatures drop off. A series of waves of low pressure will move along an west to east nearly stalled out frontal boundary from mid-week onward.
No weather surprises today with dominant ridge in proximity to the area and onshore flow developing. With lots of sun, temps will climb to the 80s across the interior remaining in the mid/upper 70s at the coast due to easterly winds and relatively cooler shelf waters. Overnight, lows will also be above normal in the low to mid 60s.
Rainfall amounts will range from a tenth to a quarter of an inch, with the higher totals across the Big Country. Highs will climb into the lower to mid 80s across most of the area.
Rainfall coverage, although light intensities, are beginning to increase across the southwest as the warm front lifts north. As the warm front lifts, rain chances decrease tonight, with the best chances in the north by sunrise. The cold front will try to work closer to the region Tuesday.
VFR conditions are expected into the early afternoon, then cigs will fall as a warm front lifts north.
