and also to lower pops for the southern hills and far southwest SD, generally to the west of Pine Ridge where downslope has become very evident. Also extended the high wind warning through Thursday afternoon for far northwest SD. Deep upper trough is parked over the upper Midwest and Northern Plains, with embedded vort maxima rotating through the flow. However, warm BL with temps expected to remain above freezing most places on the plains should help mitigate impacts. Tongue of elevate moisture will remain over much of the FA this afternoon/evening with expected bouts of rain/snow showers with little or no accums expected given warm BL above freezing. Given persistent BL wind and bufr progs for warning level wind gusts, opted to extend the high wind warning through Thur for a few additional zones east of the BH, including Rapid City.
Tonight and Thursday An upper low circulating over northwestern Wisconsin will meander around northwest and north-central Wisconsin through Thursday morning, before slowly sinking south Thursday afternoon. Up to an inch of wet snow could accumulate across far north-central Wisconsin overnight Lows tonight are expected to mainly be in the lower to middle 30s. Highs on Thursday are expected to range from around 40 across north-central Wisconsin to the lower 40s across central and east-central Wisconsin under overcast skies and steady light precipitation for most of the day.
A cold front analyzed moving across W TN and W KY will be the focus for showers and thunderstorms later this afternoon and evening. This along with at least weak solar insolation should contribute to increasing instability ahead of the cold front. Clouds continue to clear out early this afternoon ahead of a strong cold front. Scattered showers and thunderstorms are expected along the cold front from west to east late this afternoon through the evening hours.

This afternoon through Thursday night The gradient across the Cowboy State will remain tight today, with a 130kt jet digging into the base of the exiting trough. This pattern will continue into Thursday, with the gradient gradually weakening as a longwave ridge builds over the PACNW and Canadian Rockies.
Along and west of this trough axis has been the focus for a mix of rain and snow across the region overnight. This trough axis will remain over the eastern part of the forecast area today but diminish in strength and moisture during the day. Winds have diminished enough overnight to cancel the High Wind Warning. A Lake Wind Advisory for Fort Peck Lake will replace the High Wind Warning. High pressure moves in tonight with clearing skies and diminishing winds. Skies will be mostly sunny on Thursday with high pressure over the area.
302 PM EDT Wed Apr 6 2022 The cold front currently advancing through the CWA will be well east of the area by the beginning of the short term period, but some lingering post-frontal precip across the far eastern portions of the CWA are not out of the question. Though backing sfc winds switch from a cool NW flow to a warmer southerly flow overnight, steady 850mb CAA should outweigh the lighter sfc winds and allow lows overnight to be a touch cooler than climo, mostly in the upper 30s and low 40s across the board.
315 PM EDT Wed Apr 6 2022 Low pressure will pass south of the area Thursday afternoon.
(Tomorrow through Wednesday) Deep upper low will slowly rotate through the Great Lakes region over the next couple of days, which will result in breezy W-NW winds. Fire danger will be high Thursday, but offset some by cooler temperatures.
Upper level ridging will begin to build into North Dakota from the west.
257 PM CDT Wed Apr 6 2022 A vigorous mid/upper trough over the Upper Mississippi Valley area today is progged to meander over that area through tomorrow while sinking slightly southward.
For tonight into Thursday, a cold front will approach and move through the region, with scattered to numerous showers and thunderstorms expected.
Gusty northwest winds under a strong gradient up to 8-10mb through the high plains of western Kansas.
High pressure is in place bringing mostly clear skies, dry conditions, and overall light winds. Tomorrow expect much of the same weather conditions only with warmer temperatures, about 5 degrees above normal. There is a 80 to 85% chance for temperatures in the low 60s for the Eastern Magic valley, Raft River, and the lower Snake Plain.
219 PM EDT Wed Apr 6 2022 A cold front will move through the Ohio Valley today providing showers and a few thunderstorms. An upper level low centered over the Great Lakes will produce additional chances of showers and much cooler temperatures from late this week into the start of the weekend. Cold air advection will produce low temperatures in the upper 30s west to the low 40s east. For Thursday, the upper level low over the upper Midwest begins to slowly wobble southeast.
A strong and nearly vertically stacked low pressure system continues to move east into northern Wisconsin with a trough axis extending into the Missouri River Valley.
Spokes of energy rotating around the low and heating were assisting considerable clouds and areas of showers throughout the Midwest. Highs will be limited to mostly the lower to a few mid 40s. Cooler air aloft may event support some potential for wet snowflakes mixing in with the rain in some of our northern counties, as temperatures possibly lower into the upper 30s in the precip north.
In the wake of a cold front, winds are breezy from the N/NW and this will remain the case for most of the period. Isolated strong storms were still ongoing this morning as a cold front made its way through the state from the northwest. At the same time, there will be ridging over the western United States.
Cold front will lie across the eastern FL Panhandle at sunrise with ongoing precip likely across north FL but the convection should be rather weak. Pre- frontal SW flow will advect deeper moisture across EC FL, while pushing temps into the low 90s across Okeechobee and Treasure coast counties.
231 PM CDT Wed Apr 6 2022 Very strong winds continue through Thursday as deep low pressure remains centered over east central MN/northwest WI resulting in a tight pressure gradient over most of the area. While low pressure will very slowly migrate eastward over the period, its grasp will be maintained over the forecast area through Thursday before gradually being released from west to east Thursday night. Due to this, will maintain the High Wind Warning through Thursday from the James River Valley through portions of south central North Dakota.
232 PM CDT Wed Apr 6 2022 Upper low sits and spins over the Western Lakes region, with a mid level trough pinwheeling back into the Dakotas overnight.
1143 AM MDT Wed Apr 6 2022 Temperatures have rebounded back to above freezing this morning across the Grand Valley, Eastern Uinta Basin, and the Arches/Grand Flat area. Water vapor imagery is a sight to see this morning with a strong upper jet flowing over the Central Rockies and cold front plunging down the lee of this range. Temperature is just now knocking the door of freezing in the lower Colorado River Valley. With ridging moving in for Thursday temperatures in the afternoon should push to within 2 to 4 degrees either side of normal.
SKC with gusty NE winds early, fading after 21z as high pressure builds from the north. (Today through Thursday afternoon) Upper low centered over the Great Lakes region this morning has a broad trough extending down through the middle of the country. This low will continue to wrap up today. and Thursday as a ridge builds over the Western US. Early this morning a cold front is pushing through SE NM and the Permian Basin with a N wind gusting 30kts+. Looking for temps today 10 to 20 degrees cooler than yesterday with little change for Thursday.
SKC with gusty NE winds early, fading after 21z as high pressure builds from the north. (This afternoon through Thursday night) Post-frontal environment is definitely cooler than yesterday with temps a solid 15-20 degrees lower than where we were 24 hrs ago. A bit of a flex will occur overnight as amplitude of the trough favors a greater push of surface ridging over the western half of TX.
1016 AM PDT Wed Apr 6 2022 High pressure will bring drier weather for the middle of the week.
230 PM CDT Wed Apr 6 2022 Latest surface analysis is showing that the cold front has moved off well to the east into the Ohio Valley. This low will move slowly east into the western Great Lakes by tomorrow which should keep the pressure gradient tight across area, so winds will remain gusty out of the west to northwest through tomorrow. Water vapor imagery is also showing the accompanying upper low which will move in tandem into Wisconsin by late tomorrow.
Enough blowing dust could reWinds will subside tonight, aside from a wind shift to the north and northeast across eastern NM, as another back door cold front drops south through the night. The northwest winds will usher in cooler air with high temperatures approximately 10 to as much as 30 degrees cooler than yesterday.
409 PM EDT Wed Apr 6 2022 Active weather is expected to close out the work week as a large trough slowly drifts east across the eastern half of the country.
(This evening through Thursday) Cooler temperatures expected today and Thursday after the cold front from earlier this morning tracked through the area bring gusty winds along with it. Even with these cooler conditions, we are still seeing critically dry conditions across West Central Texas, along with gusty winds gusting as high as 35 MPH through the afternoon hours.
In addition, a cold front is moving into northern Mississippi with much cooler and drier air behind it. MLCAPE values are currently around 2500 J/Kg around the area with temperatures in the low 80s and dewpoints in the upper 60s to around 70. The cold front will move through the area this evening into early Thursday morning with additional development along and ahead of the boundary. A much cooler and drier airmass moves into the area in the wake of the front.
127 PM EDT Wed Apr 6 2022 Periodic precipitation chances are expected through the week and weekend with a persistent low pressure pattern. Above normal highs are forecast with southerly flow ahead of approaching low pressure. While profiles will show skinny areas of CAPE, sufficient shear aloft will aid in development of thunder with added forcing from the cold front. Throughout the rest of the week, the low pressure over the Great Lakes will progressively mature and cut-off.
/Issued 1225 PM CDT Wed Apr 6 2022/ /This Afternoon through Thursday Night/ High pressure continues to build into North Texas today and winds will gradually diminish through the afternoon. Otherwise, a fairly cool night is in store with lows expected in the low/mid 40s with light winds.
Winds this afternoon have become quite gusty out of the northwest as they spin around the low. Additionally, dry air a surged into the area after yesterdays cold front.
1237 PM CDT Wed Apr 6 2022 - Cooler today with westerly wind gusts as high as 35 mph and elevated fire weather conditions this afternoon.
This is not surprising given that a upper level ridge is situated over the western Caribbean and across Cuba which has stifled vertical growth. Why is this important? Southerly flow will continue across the region tonight due to our location being on the western periphery of a low level ridge. Meanwhile, PoPs will remain on the low side through Thursday as we prepare for a late season frontal passage.
1259 PM CDT Wed Apr 6 2022 (Today and tonight) Early this morning, a cold front is racing southward toward the Texas Hill Country. The cooler airmass moving in will lead to high temperatures today in the low to mid 70s.
222 PM MDT Wed Apr 6 2022 Snow from this morning has changed over to all rain as northeast Montana remains on the backside of the large low pressure system. The lower clouds stretch across most of northeast Montana as rainfall continues general along and about 100 miles either side of a line from Whitewater through Glasgow through Terry.
328 PM CDT Wed Apr 6 2022 Clouds and a few showers are moving through the Mid South this afternoon as a cold front has moved through the region. The next few days will be much cooler across the forecast area as temperatures will be much cooler going into the weekend.
135 PM MDT Wed Apr 6 2022 Water vapor shows main upper low over the Upper Midwest, with northwest/north flow aloft and notable vort lobes rotating through the flow across southern SASK/Manitoba into ND. High Winds Warnings will remain in effect for much of the western SD plains, and it's probable that a Wind Advisory for far southwest SD will need to be issued once the High Wind Warning for that area expires late tonight.
Despite much cooler temperatures than yesterday, a very dry airmass has settled in behind the cold front that pushed south through our area last night. The lighter winds and mostly clear skies will result in cooler temperatures overnight, including sub-freezing temperatures across most portions of the western South Plains by sunrise tomorrow. The far western South Plains remains out of the watch for now where weak surface ridging tomorrow will help mitigate the stronger winds.
420 PM EDT Wed Apr 6 2022 A cold front will move through the region into the evening hours.
High pressure will bring warmer and drier conditions to Western Washington through Thursday.
The cold frontal boundary is now moving into our far northwestern forecast zones at this time, and increased convergence associated with the front in the very unstable airmass has fired a few stronger storms along the boundary.
642 PM CDT Wed Apr 6 2022 A vigorous mid/upper trough over the Upper Mississippi Valley area today is progged to meander over that area through tomorrow while sinking slightly southward.
901 PM EDT Wed Apr 6 2022 Scattered showers are slowly pushing toward the east this evening as drier air works in behind a cold front. The cold front currently advancing through the CWA will be well east of the area by the beginning of the short term period, but some lingering post-frontal precip across the far eastern portions of the CWA are not out of the question. Though backing sfc winds switch from a cool NW flow to a warmer southerly flow overnight, steady 850mb CAA should outweigh the lighter sfc winds and allow lows overnight to be a touch cooler than climo, mostly in the upper 30s and low 40s across the board.
744 PM EDT Wed Apr 6 2022 Active weather is expected to close out the work week as a large trough slowly drifts east across the eastern half of the country.
Dry and warmer weather is in store through Thursday.
319 PM MDT Wed Apr 6 2022 Its been a mostly sunny and cool by seasonal standards day across eastern Utah and western Colorado in the wake of yesterday's cold front. After a chilly morning, temperatures have trended 5 to 10 degrees cooler than this time yesterday afternoon. Breezy post- frontal winds have also developed with northerly gusts of 25 to 35 mph reported in several lower valleys with stronger winds at the higher elevations. Another subfreezing night is on tap for the region as clear skies and light winds will support strong radiational cooling into Thursday morning. While subfreezing temperatures are expected elsewhere, vegetation has not been declared susceptible at this time. Thursday will see the ridge of high pressure building off of the west coast slide east to settle over the Great Basin.
626 PM CDT Wed Apr 6 2022 A cold front and associated rain showers have exited our forecast area to our east. An area of heavier precipitation is moving through northeastern Iowa and throughout most of Wisconsin as the an area of vorticity is rotating around the low, enhanced by the left exit region of the upper jet. Cooler temperatures are expected Thursday, with highs only reaching the mid to upper 40s Thursday.
(This afternoon through Thursday night) Post-frontal environment is definitely cooler than yesterday with temps a solid 15-20 degrees lower than where we were 24 hrs ago. A bit of a flex will occur overnight as amplitude of the trough favors a greater push of surface ridging over the western half of TX.
653 PM CDT Wed Apr 6 2022 (This evening through Thursday) Cooler temperatures expected today and Thursday after the cold front from earlier this morning tracked through the area bring gusty winds along with it. Even with these cooler conditions, we are still seeing critically dry conditions across West Central Texas, along with gusty winds gusting as high as 35 MPH through the afternoon hours.
The cold front currently advancing through the CWA will be well east of the area by the beginning of the short term period, but some lingering post-frontal precip across the far eastern portions of the CWA are not out of the question. Though backing sfc winds switch from a cool NW flow to a warmer southerly flow overnight, steady 850mb CAA should outweigh the lighter sfc winds and allow lows overnight to be a touch cooler than climo, mostly in the upper 30s and low 40s across the board.
1053 PM EDT Wed Apr 6 2022 Currently - A surface through lower level ridge extends westward across the Bahamas and the Florida Straits. This along with the ridging has prevented shower activity within the forecast area this evening. Short Term Update - Despite the approaching frontal system, the surface through lower level ridging will largely retain control across our area through the overnight period even as it begins retreating eastward. As the ridge retreats, lower level confluent flow will begin to encroach southeastward into our deep gulf waters. In addition, a ribbon of moisture rich lower level flow will continue to wrap north and northeastward around the ridge axis. A ridge across the Florida Straits will retreat eastward overnight.
This will be a relatively short lived fog event, as a cold front will sweep east across the area by shortly after midnight and a moderate to strong, drier northwesterly flow develops over the area. The cold frontal boundary is now moving into our far northwestern forecast zones at this time, and increased convergence associated with the front in the very unstable airmass has fired a few stronger storms along the boundary.
706 PM EDT Wed Apr 6 2022 A cold front will move through the region into the evening hours.
541 PM EDT Wed Apr 6 2022 Periodic precipitation chances are expected through the week and weekend with a persistent low pressure pattern. Throughout the rest of the week, the low pressure over the Great Lakes will progressively mature and cut-off.
637 PM CDT Wed Apr 6 2022 Latest surface analysis is showing that the cold front has moved off well to the east into the Ohio Valley. This low will move slowly east into the western Great Lakes by tomorrow which should keep the pressure gradient tight across area, so winds will remain gusty out of the west to northwest through tomorrow. Water vapor imagery is also showing the accompanying upper low which will move in tandem into Wisconsin by late tomorrow.
Water vapor shows main upper low over the Upper Midwest, with northwest/north flow aloft and notable vort lobes rotating through the flow across southern SASK/Manitoba into ND. High Winds Warnings will remain in effect for much of the western SD plains, and it's probable that a Wind Advisory for far southwest SD will need to be issued once the High Wind Warning for that area expires late tonight.
/issued 328 PM CDT Wed Apr 6 2022/ Clouds and a few showers are moving through the Mid South this afternoon as a cold front has moved through the region. The next few days will be much cooler across the forecast area as temperatures will be much cooler going into the weekend.
1000 PM EDT Wed Apr 6 2022 Update With the upper low moving in overhead tomorrow afternoon into the evening.
949 PM CDT Wed Apr 6 2022 Cold frontal boundary has cleared the region this evening, with the exception of maybe a small portion of the coastal waters. Drier and cooler air will continue to advect into the region overnight, with morning lows in the upper 40s to low 50s.
