1112 AM CST Fri Mar 3 2023 (Today through Saturday) Cold front moved through the CWA around midnight bringing gusty northwesterly winds behind it. Mostly clear skies are expected today with high temperatures feeling much cooler reaching only the mid 80s.
With the exception of Mcdonough, Bureau and Putnam counties in northwest Illinois, all of us were dry thanks to very dry north winds from high pressure centered over northern Quebec. tonight, allowing an area of high pressure currently over eastern Texas to build over the area. This high will keep our weather dry and quiet through early Saturday, even bringing some breaks in the cloud cover tonight.
120 PM EST Fri Mar 3 2023 A strong low pressure system will track across the Ohio Valley today and into the Great Lakes tonight. As the system departs, high pressure returns for the weekend with dry conditions. Strongest synoptic winds look to arrive as the system wraps up after the cold front moves thru the area this evening. Strong low level cold air advection in the wake of the cold front will result in northwest sustained winds of 20-30 MPH with gusts up to 50 MPH possible.
A Wind Advisory will continue to be in effect until the late afternoon, with the High Wind Warning in the Delta allowed to expire at noon as the gradient slowly relaxes. Expect wind to diminish quickly for tonight with a much cooler airmass allowing temperatures to dip well into the 40s.
We have seen several gusts of 60 MPH and this would verify the High Wind Warning. The High Wind Warning remains in effect through 6 PM this evening. A low pressure system will track through the Mid-South this morning. This low will drag a cold front through the region. Showers and thunderstorms will be found ahead of the cold front. Winds will be very strong outside of the thunderstorms and behind the cold front.
Westerly winds and clear skies allowing temps to climb into the low 30s and a couple 40s in the MN trees at Itasca and Kelliher. Southerly winds are decreasing in the southern valley and NW MN as trough approaches with clearing skies from the west. This scenario will allow temps to climb into the low to mid 30s with some higher readings possible in the trees as the absorb heat better from the stronger March sun. Hard to say cold front though, as there is no real push of colder air behind it. Highs look a bit cooler than today, but still close to normal.
The fact that we already have convective snow upstream also adds confidence that we will see the higher rates.
1039 AM CST Fri Mar 3 2023 Gradient remains tight over South Texas in the wake of the exiting low pressure system currently moving into Southern Illinois and winds have been gusting higher than guidance indicates. Winds should relax sharply by noon as high pressure settles into the region revealing a very nice day across South Texas with low humidities and mild/warm temperatures with highs in the upper 70s east to mid 80s west. Winds will shift to weak onshore by this evening as the high pressure ridge moves into the northwest Gulf of Mexico. Upper level flow will become zonal for Saturday with slightly warmer temperatures in store.
1042 AM CST Fri Mar 3 2023 Southerly winds are decreasing in the southern valley and NW MN as trough approaches with clearing skies from the west. This scenario will allow temps to climb into the low to mid 30s with some higher readings possible in the trees as the absorb heat better from the stronger March sun. Hard to say cold front though, as there is no real push of colder air behind it. Highs look a bit cooler than today, but still close to normal.
1110 AM CST Fri Mar 3 2023 (Today through Saturday afternoon) We are finally seeing winds wind down across our region as the robust upper level low responsible for the wind storm yesterday continues to depart ewd towards the ArkLaTex. A weak cold front (emphasis on weak) will arrive early Saturday bringing a brief northerly wind shift. This will allow high temps to top out above normal in the low to mid 70s in most locations.
Yet, it has remained dry thanks to mean layer ridging centered to our east. This low in combination with its parent upper level trough is displacing the mean layer ridge that has been dominating our sensible weather.
Temperatures are then expected to climb into the 60s to low 70s Saturday with the cooler temperatures in NW parts of the fa.
The winds should subside greatly by 5-6 pm, but until then, we will maintain the High Wind Warning. Lows tonight will drop into the lower 40s.
It'll be a cool night under clear skies with temperatures falling into the lower 40s areawide. A fantastic Saturday is expected with highs climbing back into the lower 70s and light southerly winds.
241 PM CST Fri Mar 3 2023 A record setting low pressure system (977mb) is beginning to depart to the northeast of the KEVV area.
The surface pressure low that accompanied it has also moved away, weakening our pressure gradient and winds, leaving our area in a dry and cooler air mass with clear skies. Lows will drop down into the low to mid 40s for the most part, although a few readings in the upper 30s can't be ruled out.
moist and unstable zonal flow aloft will persist over the Northern Rockies through this evening before the pattern shifts to more southwesterly through the day on Saturday as a longwave trough digs south over the Eastern Pacific.
This is because a potent weather maker is moving through the Mississippi River Valley with a trailing cold front draped across the central Gulf of Mexico. Otherwise, temperatures are in the lower 80s with dew points in the upper 60s to lower 70s. Breezes will further slacken Saturday as a cold front stalls well to our north across the Gulf of Mexico and the Sunshine State.
Tomorrow will be even warmer despite the passage of a weak "cold" front during the day. The cool air mass behind the front will be so shallow, that it will mix out during afternoon heating allowing warmer temps aloft to mix down and warm the area to the 70s.
131 PM MST Fri Mar 3 2023 Water vapor shows short wave moving through WY with broad trof offshore the Pac NW coast. At the surface, cold front that moved through overnight and this morning has shifted well south of the forecast area. For Saturday, short wave ridge behind departing short wave trof will bring dry west/southwest winds and highs into the 30s through mid 40s, warmest east of the Black Hills.
These higher gusts will continue behind the line as the cold front approaches and moves through and a High Wind Warning continues for all areas through this evening. Temperatures fall into the upper 30s to low 40s late tonight behind the cold front. Temperatures will be cooler with highs in the lower 50s to low 60s.
(This afternoon through Saturday Night) An incredibly strong 979 mb low pressure center currently located near EVV continues to deepen rapidly, hence the unusually strong winds over Middle Tennessee. We do anticipate being able to clear these counties as soon as storms move out, although the high wind warning will remain. Fortunately, we are done with active weather for awhile after today, and temperatures this weekend are going to be a little cooler as post-frontal air advects into Middle Tennessee from the northwest.
1014 AM EST Fri Mar 3 2023 14z surface analysis reveals well-advertised low pressure centered across southeast MO with widespread precipitation working across central IL and areas east into the Ohio Valley. Latest trends suggest steady northeastward of low pressure today. A developing low pressure system over the Ohio Valley will continue to move northeast and produce some snow over the very southeastern part of the forecast area. This low will begin filling as it begins to impact northern Michigan. High pressure and much drier air will move in quickly behind this departing system.
At the same time, expect clouds to lift northward with the low.
1052 AM CST Fri Mar 3 2023 (Today through Saturday Night) The cold front has pushed to the east ushering in cooler, drier air that will stick around through Saturday. Breezy northwesterly winds of 10 to 15mph and occasional higher gusts will persist through the afternoon today as the low pressure system pulls away to the northeast. High pressure builds in over East Texas today that slides into the lower Mississippi river valley on Saturday keeping the drier conditions in place for us in SE Texas. We can expect temperatures this afternoon to climb into the low 70s along and south of I-10 and then in the upper 60s north of Conroe. Saturday night will be cool, but not as cool as tonight, with temperatures dropping down into the low to mid 50s across the area.
Upper trof moving across the southern Plains will take on a negative tilt as it moves northeastward across the Ozarks this morning and into the lower Ohio Valley later this afternoon. Thermal profiles under the deformation zone of the departing upper trof look to remain marginal for frozen precip this morning, though could see a brief transition or mix across parts of south central Kansas and the Flint Hills.
Farther south, clouds are still in place, but temperatures are above freezing, so some melting is still taking place. Temperatures around the area are in the low 30s to mid 40s.
1154 AM CST Fri Mar 3 2023 (Today and tonight) Early morning upper-level water vapor imagery and RAP analysis showed the upper low that brought light precipitation and breezy/cool conditions to the area moving south of the Red River towards I-35.
RAP synoptic/sfc analysis indicates upper low is quickly swinging to the NE out of the MO Bootheel into W Kentucky. The sfc cold front is quickly moving E into central to eastern AL. Light winds combined with cooler thermo/partly cloudy skies will support lows falling into the mid-upper 40s. Saturday: W-SW flow aloft & mean ridging will build through the region to start the weekend. Combined with cooler low-level thermo profiles & W-NW low-level flow, quiet, dry & slightly cooler aftn is in store.
31 (This afternoon through Saturday) 500mb analysis shows an upper low across eastern MO. A negatively tilted trough extends to the southeast of the low into the Lower Mississippi River Valley. The upper low will continue to move into the central Great Lakes Region this evening. At the surface, a low pressure is centered across W KY/far S IL. This low will rapidly move east this evening into the east-central Great Lakes Region. A line of strong/severe thunderstorms has developed out ahead of the cold front and will move through the CWA later this afternoon into the early evening hours.
A cold front remains just to our west, with strong gradient winds impacting the terminals through the afternoon. The cold front will pass through the area this evening, with winds subsiding through the overnight hours. /73 (Now through Saturday) A potent upper low continues to move slowly to the east, currently making its way into the Ohio Valley. At the surface, the parent low was located over the Missouri Bootheel, with a cold front extending through western Tennessee, southward through Mississippi. These will diminish this evening as the cold front passes and the pressure gradient relaxes.
1129 AM CST Fri Mar 3 2023 (Today and tonight) Upper low will continue to shift northeast today with a few lingering showers this morning across portions of north-central into eastern parts of the area. Other than the cold core of the upper low, no real cold air associated with the system, so we should see warmer temperatures across at least the northern half of the area by the afternoon hours today.
1208 PM EST Fri Mar 3 2023 14z surface analysis reveals well-advertised low pressure centered across southeast MO with widespread precipitation working across central IL and areas east into the Ohio Valley. Latest trends suggest steady northeastward of low pressure today. A developing low pressure system over the Ohio Valley will continue to move northeast and produce some snow over the very southeastern part of the forecast area. This low will begin filling as it begins to impact northern Michigan. High pressure and much drier air will move in quickly behind this departing system.
1027 AM MST Fri Mar 3 2023 Current surface map places warm front across the central Dakotas with cold front moving into eastern Montana. For today, cold front drops into northeast Wyoming and north South Dakota this morning and trough the rest of the forecast area this afternoon.
Will be fighting some low level dry air so confidence in getting much at the surface is pretty low, thus the low chances and low amounts. The warmest readings will be in northwest IA in the lower to mid 40s, while most of the area will be from 35 to 40.
231 PM EST Fri Mar 3 2023 (This afternoon through Saturday) 500mb analysis shows an upper low across eastern MO. A negatively tilted trough extends to the southeast of the low into the Lower Mississippi River Valley. The upper low will continue to move into the central Great Lakes Region this evening. At the surface, a low pressure is centered across W KY/far S IL. This low will rapidly move east this evening into the east-central Great Lakes Region. A line of strong/severe thunderstorms has developed out ahead of the cold front and will move through the CWA later this afternoon into the early evening hours.
(This evening through Saturday) The cold front is moving southeast near Montgomery to Wedowee. These winds will start subsiding as the gradient relaxes and the highest winds aloft exit eastbound. There still remains some question on how far south and east the lower clouds get.
519 PM CST Fri Mar 3 2023 (Through Tonight) The back edge of the low clouds is slowly making its way eastward across eastern Oklahoma, having reached Highway 75.
A record setting low pressure system (977mb) is beginning to depart to the northeast of the KEVV area.
A high pressure ridge will briefly build this evening, shunting shower activity north and east, and eventually ending all activity around midnight.
LGB (This afternoon through Saturday) 500mb analysis shows an upper low across eastern MO. A negatively tilted trough extends to the southeast of the low into the Lower Mississippi River Valley. The upper low will continue to move into the central Great Lakes Region this evening. At the surface, a low pressure is centered across W KY/far S IL. This low will rapidly move east this evening into the east-central Great Lakes Region. A line of strong/severe thunderstorms has developed out ahead of the cold front and will move through the CWA later this afternoon into the early evening hours.
318 PM MST Fri Mar 3 2023 Snow rates will decrease across western Wyoming this afternoon and evening as the trough axis begins moving off to the east. Currently, a weak cold front is beginning to push down into northern Wyoming. The front will stall east of the Divide tonight as a brief transitory ridge builds in.

This low will rapidly move east this evening into the east-central Great Lakes Region. A line of strong/severe thunderstorms has developed out ahead of the cold front and will move through the CWA later this afternoon into the early evening hours.
An upper trough, currently located across western Wyoming and far eastern Utah will move across the forecast area tonight. A cold front will move in later tonight behind the system. On Saturday, a slight chance for light snow is possible until mid morning across the northeast as the upper trough exits the area. Slightly cooler from the upper 30s to lower 40s with weak mixing expected.
646 PM EST Fri Mar 3 2023 A very strong low pressure system will track through the area this evening and continue off to the east overnight. High pressure will build in Saturday and persist through the weekend.
818 PM CST Fri Mar 3 2023 Gradient remains tight over South Texas in the wake of the exiting low pressure system currently moving into Southern Illinois and winds have been gusting higher than guidance indicates. Winds should relax sharply by noon as high pressure settles into the region revealing a very nice day across South Texas with low humidities and mild/warm temperatures with highs in the upper 70s east to mid 80s west. Surface winds have dropped to less than 10 knots most areas as the ridge axis settles along the coast. Winds will become onshore late this afternoon and early evening as the ridge axis shifts east. Warm and dry conditions can be expected Saturday with highs in the 80s as a flat ridge persists aloft.
Tonight and Saturday Synopsis: Strong low pressure will travel northeast from the northern Ohio Valley to the eastern Great Lakes.

(Through Saturday) A cold front will push through the area overnight tonight with a few showers still possible along it. (Saturday night through Friday) The main concern will be with the potential for a stronger cold front to makes its way into the region toward Friday.
414 PM EST Fri Mar 3 2023 A very strong low pressure system will track through the area this evening and continue off to the east overnight. High pressure will build in Saturday and persist through the weekend.
Cloud cover filtering into the island chain from the southwest is associated with a cold front draped over the central Gulf of Mexico. The cold front will continue to move eastward over the next several days and become diffuse near central Florida.
348 PM MST Fri Mar 3 2023 Snow rates will decrease across western Wyoming this afternoon and evening as the trough axis begins moving off to the east. Currently, a weak cold front is beginning to push down into northern Wyoming. The front will stall east of the Divide tonight as a brief transitory ridge builds in.
518 PM CST Fri Mar 3 2023 (This afternoon through Saturday Night) An incredibly strong 979 mb low pressure center currently located near EVV continues to deepen rapidly, hence the unusually strong winds over Middle Tennessee. We do anticipate being able to clear these counties as soon as storms move out, although the high wind warning will remain. Fortunately, we are done with active weather for awhile after today, and temperatures this weekend are going to be a little cooler as post-frontal air advects into Middle Tennessee from the northwest.
Have allowed the High Wind Warning to quietly expire at 00Z. The highest gusts we had reported was 80 mph in Clarksville and possibly another 80 mph in Livingston. Definitely a bit cooler than the last several days.
(This evening through Saturday night) 21z surface analysis shows the cold front has moved east of the forecast area and was near Mobile Bay as evident by the veered westerly winds behind it vs southwesterly ahead of it. Winds will continue to quickly diminish through the evening hours as high pressure builds in from TX. The center of the high will pass to our north on Saturday but the ridge axis will move overhead.
926 PM EST Fri Mar 3 2023 A very strong low pressure system will track through the area this evening and continue off to the east overnight. High pressure will build in Saturday and persist through the weekend.
Breezy south winds were felt across the area today ahead of the approaching cold front, but wind speeds have started subsiding this evening as day time heating comes to an end. With the wind speeds dropping, the High Surf Advisory was allowed to expire at 7 PM, although onshore swells will keep the threat of rip currents in place through Saturday evening.
422 PM MST Fri Mar 3 2023 Water vapor shows short wave moving through WY with broad trof offshore the Pac NW coast. At the surface, cold front that moved through overnight and this morning has shifted well south of the forecast area. For Saturday, short wave ridge behind departing short wave trof will bring dry west/southwest winds and highs into the 30s through mid 40s, warmest east of the Black Hills.
534 PM CST Fri Mar 3 2023 (This evening through Saturday night) 21z surface analysis shows the cold front has moved east of the forecast area and was near Mobile Bay as evident by the veered westerly winds behind it vs southwesterly ahead of it. Winds will continue to quickly diminish through the evening hours as high pressure builds in from TX. The center of the high will pass to our north on Saturday but the ridge axis will move overhead.
(Now through Saturday) A cold front, currently bisecting the forecast area, will continue to move slowly eastward this afternoon. Little in the way of convection has occurred due to a lack of forcing associated with the front and its upper trough/low. The trough will continue to eject well northeast of the area, with flow aloft becoming zonal this evening. Zonal flow will persist through Saturday, with surface flow veering to the north as high pressure builds over the region. A fairly pleasant Saturday is in store in the wake of the aforementioned front, with highs topping out in the lower 70s across our northern counties and upper 70s along the coast.
948 PM CST Fri Mar 3 2023 We are rapidly losing the low wraparound cloud cover across SW AR and NE LA this evening. Sfc ridging is directly ovhd attm as well and combine that with clear skies and the dry atmosphere in place, temperatures are falling rapidly. At the same time, expect clouds to lift northward with the low.
123 AM EST Sat Mar 4 2023 The cold front has moved east of the forecast area and will shift off the coast by Saturday morning.
1057 PM CST Fri Mar 3 2023 (This evening through Saturday) The cold front is moving southeast near Montgomery to Wedowee. These winds will start subsiding as the gradient relaxes and the highest winds aloft exit eastbound. There still remains some question on how far south and east the lower clouds get.
With the winds decreasing in strength will go ahead and cancel the High Wind Warning in this area a few hours early, replacing it with an SPS about some breezy conditions through sunrise. At sunrise conditions will be much cooler than the past several days with low dropping out in the 30's or 40's.
315 AM EST Sat Mar 4 2023 Low pressure will move east of the region today with precipitation slowly coming to an end.
Winds will shift to the north and northeast behind this boundary along with some slightly cooler air, keeping temps across the north and west a few degrees cooler than elsewhere today. Some models are also showing some signs of a bit more cloud cover which will also contribute to a bit cooler afternoon in these areas. This boundary will wash out tonight with south winds returning as pressure falls occur across the High Plains in advance of upper wave moving through intermountain west.
Water vapor shows short wave moving through WY with broad trof offshore the Pac NW coast. At the surface, cold front that moved through overnight and this morning has shifted well south of the forecast area. For Saturday, short wave ridge behind departing short wave trof will bring dry west/southwest winds and highs into the 30s through mid 40s, warmest east of the Black Hills.
A secondary/reinforcing cold front is also dropping southward into the area, with slightly cooler/drier air in tow. With the sfc wind field also relaxing, current temps in the upper 50s/lower 60s look to fall well into the lower 40s for most spots late tonight.
