Meanwhile, a cold front will move through West Central Texas through the mid morning hours, with breezy northerly winds of around 10-15 mph with gusts of 20-25 mph coming in behind the front which will continue through the afternoon. With the cold air coming in, expect cooler conditions today, with highs in the mid 50s in the Big Country, and upper 50s/low 60s elsewhere.
340 AM CDT Fri Mar 20 2020 A cold front was located just north of the area early this morning, stretching from southeast Kansas into the west central Missouri. Ahead of the front, temps were generally in the lower 60s across the area with mostly clear skies. The cold front will sweep through the area this morning, therefore a non diurnal temperature range is expected today with temps falling and perhaps leveling off by afternoon into the 40's. North winds will make it feel much cooler, with wind gusts of 20-30mph possible for the first half of the day.
345 AM CDT Fri Mar 20 2020 A stout cold front is currently racing through the CWA, with drastically cooler temperatures and gusty north winds immediately behind it. The front will continue through the area today as high pressure builds into the Northern Plains.
With a hefty western Atlantic ridge axis extending across the Florida Peninsula, a low level easterly flow will allow a few patches of higher moisture to be guided westward and across our area. The persistent high pressure cell over the Sunshine State and the adjacent Gulf and Atlantic waters will sag southward and flatten over the next couple of days, before building back over our region.
921 AM CDT Fri Mar 20 2020 Have updated pops over the lakes region of southeast Texas and central Louisiana thru the day today has a cold front approaches from the west. /issued 635 AM CDT Fri Mar 20 2020/ MVFR conditions are expected through most of the forecast period as a cold front slowly moves through the area. Elsewhere, a cold front moving through OK/N TX will be moving through the region later today. Temperatures this morning are still ridiculously in the lower to mid 70s, some 20+ degrees above normal. The wind pattern aloft is primarily influenced by the large mid/upper level trof over the Western U.
A warming trend gets underway for central and western New Mexico today while the east cools down behind a backdoor cold front.

Cold front will be from near KFYV-KMLC by 12z and will continue to push through remainder of SE OK and NW AR through mid morning. /Issued 340 AM CDT Fri Mar 20 2020/ Strong cold front currently pushing through NE OK with broad region of 5-8mb/3hr pressure rises noted upstream which will help maintain strong post frontal winds through the morning hours. Broad region of convection which is expanding through central TX will spread northeastward ahead of the advancing cold front with a slight chances of showers into far SE OK. The persistent wave train downstream of the E Pacific blocking ridge will remain in place through the upcoming week.
Throughout the day, a strong cold front will progress southward across the state. Winds will increase and drier/cooler air will filter in. The flow aloft will remain out of the SW while surface ridging pushes south. Cold air will be in place and lows Saturday morning could fall below freezing across northern Arkansas as well as isolated locations across the west.
Cold high pressure building out of Canada shunts eastward rather quickly to elongate the boundary over the forecast area tonight, thereby causing the attendant moisture to diverge towards daybreak Saturday. Models show gulf breeze process to augment the frontal zone on Saturday's daytime heating to produce warm frontogenesis that slow lifts northward Saturday evening/night.
619 AM EDT Fri Mar 20 2020 Occasional showers and thunderstorms are expected today with crossing low pressure. Dry and cooler weather should return for the weekend under high pressure. 4 inches), and dewpoints in the low-60s will create impressive rainfall rates. With temperatures lingering in the low-70s low- level lapse rates will steepen and windy conditions (gusts near 30-35mph) will occur quickly after sunrise. By late morning, mid- level dry is anticipated to quickly advance into Western PA prior to the passage of a cold front. In the wake of the cold front, a tight pressure gradient is expected to linger. Gusts up to 35 mph may continue across the region (40 mph in the ridges) tonight and early tomorrow morning.
Winds have slowly decreased overnight and will continue to do so this morning as high pressure moves into the area.
543 AM MDT Fri Mar 20 2020 Showers are still ongoing across the forecast area of a scattered convective nature with light rain in the lower valleys and light snow at the higher elevations. The upper low is still hanging back over the Great Basin but will begin to elongate and become cut off from the main upper level trough as it retrogrades back to the west over California. Not expecting any significant snow accumulations in the high country today with maybe another 2 to 4 inches, so no highlites anticipated.
Models show weak short wave ridging over the CWA this morning. The low level winds will be easterly this morning, then more southeasterly this afternoon. There is a bit of CAPE in the high country today. For temperatures, today highs look to be some 0-2 C cooler than yesterday's highs. A weak upper level trough will move across the area late Sat into early Sun. Thus, will see an increasing chc of snow showers, over the higher terrain Sat aftn, which will continue thru the night into Sun morning. By Wed, an upper level trough will intensify over the wrn US with increasing southwesterly flow aloft. The low level Stratus cloudiness in place should remain in place until around 18Z today.
This feature will shift east mainly out of the area around 18z, however next area of lift and trailing deep moisture with the actual cold front will be pushing onto the Cumberland Plateau early this afternoon. Temperatures a little tricky but with warm air advection and a bit of a break between the trough and the frontal precipitation, maxes should still be in the ballpark. Rain increases in coverage today ahead of a cold front.
Southwest flow aloft will persist over the region with a broad upper trough situated over the Western CONUS on Friday. Temperatures will range from the low 30s in the north to the upper 30s in the south for highs.
358 AM MDT Fri Mar 20 2020 Low pressure currently centered over Nevada will keep cool and unsettled conditions over Utah and southwest Wyoming through the forecast area into the first half of the weekend.
The Desert Southwest will have a brief hiatus with dry conditions for the end of the weekend before the next low pressure system increases precipitation chances.
A cold front is progressing southward across the region this morning, accompanied by elevated/gusty northerly winds. /issued 308 AM CDT Fri Mar 20 2020/ Current obs across west TX indicate the expected cold front is positioned to the north between Lubbock and the northern tier of the Permian Basin. Front will continue to push south on the leading edge of high pressure nosing out of Canada. Cold front will slide through the Basin by early morning and the rest of the forecast area by early afternoon creating a breezy, drier, and cooler setup compared to the previous succession of days. Conditions will be quiet for much of the region over the course of Friday, but tightening pressure gradient behind the cold front across the Guadalupe's will generate a period of higher gap winds through Guadalupe Pass later this evening.
Scattered showers will continue over our area through this evening mainly over the higher elevations.
In addition, decreased winds(when compared to previous 24 hour winds), should be noted over the CWA in combination with well below seasonal temperatures as evidenced by many eastern locations struggling to reach the lower to mid 40 temperature range this afternoon. upper trough will shear eastward across Colorado Saturday, bringing scattered showers to much of the area from early afternoon into the evening.
The atmosphere remained warm and humid with temps and dew points in the low to mid 60s. The morning maps showed low pressure over the Great Lakes with a trailing cold front down through the Ozarks. Regarding thunderstorms, SB capes out ahead of the cold front will remain from a few hundred to as much as 1000 J/kg depending on how many thin spots develop in the clouds. A cold front will work slowly across the terminals today with scattered showers ahead of it.
Temperatures will be cooler, with ongoing cold advection keeping the diurnal response to a minimum - mainly in the 30-35 degree range, though it is late March so any sunshine will only help matters. High pressure slides through the area tonight into Saturday with quiet but continued chillier weather, before we watch the evolution of another northern stream wave working into the area Saturday night.
645 AM CDT Fri Mar 20 2020 A stout cold front is currently racing through the CWA, with drastically cooler temperatures and gusty north winds immediately behind it. The front will continue through the area today as high pressure builds into the Northern Plains.
Southwest flow aloft will persist over the region with a broad upper trough situated over the Western CONUS on Friday. Temperatures will range from the low 30s in the north to the upper 30s in the south for highs. a cut-off upper low offshore the central Pacific coast and split flow aloft over the western CONUS -- will persist through the weekend. DPVA attendant this feature -- and low-level warm advection on the eastern periphery of an associated lee cyclone -- are anticipated to result in the development of scattered convection in southeast Colorado late Saturday afternoon, progressing ENE into Kansas Saturday evening.
/issued 238 AM CDT Fri Mar 20 2020/ The cold front has pushed through the FA and is bringing cooler temps with it. The GFS however is roughly 10 degrees warmer as a result of clear skies. The forecast will reflect more of the GFS for highs but still remain slightly cooler as surface flow will be out of the east. Tonight will be quiet other than temperatures getting near to below freezing across the FA. Cool surface ridging will persist into the the first half of the weekend.
Expect these breezy conditions to persist into the daylight hours this morning before falling off as the center of the high pushes east. High pressure will shift east overnight into Saturday morning.
Current look at WV satellite reveals an upper low over CA/NV and a potent upper wave translating eastward across Iowa.
(Today and tonight) Breezy north winds will continue behind the cold front most of this morning.
713 AM EDT Fri Mar 20 2020 Strong northwest to north winds behind a cold front today ushers in much colder air with temperatures falling through the 40s and into the 30s by evening.
Clouds and light precipitation will stay confined to the southern half of the state, due to the circulation around the upper low. Skies are expected to clear through the overnight hours Friday night, as the upper low retrogrades toward CA.
Highs expected to be a few degrees warmer than yesterday, in the upper 80s inland, while the seabreeze caps coastal areas in the low to mid 80s.
617 AM CDT Fri Mar 20 2020 (Today and tonight) Breezy north winds will continue behind the cold front most of this morning.
735 AM EDT Fri Mar 20 2020 A broad upper ridge remains over the southeast states with a general southwest upper flow over our area. A cold front extending through the MS and OH Valleys this morning will drift south into the TN Valley by this evening. Showers and isolated thunderstorms will develop and spread into north and central GA today and tonight as a pre-frontal trough and short wave cross the area. An upper trough deepening to our north should help push the front into central GA late tonight where it should stall.
Winds will transition to a NW-N direction throughout the day as a cold front moves across the state, winds could gust to near 20kts at times. Throughout the day, a strong cold front will progress southward across the state. Winds will increase and drier/cooler air will filter in. The flow aloft will remain out of the SW while surface ridging pushes south. Cold air will be in place and lows Saturday morning could fall below freezing across northern Arkansas as well as isolated locations across the west.
Approaching 09Z (4 AM CDT) regional surface observations showing temperatures ranging from mid 60s to lower 70s, with dewpoints generally in the lower 60s. This shift due to surface cold front finally pushing into northwestern portions of mid state region early this afternoon and slowly progressing southeastward as afternoon hours progress.
At the surface, a cold front will move through the area today, enhancing low-level convergence for convective development. Rain chances will end from north to south this evening as drier air moves into the area in the wake of the cold front. We're looking for a pleasant Saturday across the Mid-South with afternoon highs tomorrow generally in the 50s, although some areas in northeast MS will warm into the lower 60s.
632 AM EDT Fri Mar 20 2020 Occasional showers and thunderstorms are expected today with crossing low pressure. Dry and cooler weather should return for the weekend under high pressure. 4 inches), and dewpoints in the low-60s will create impressive rainfall rates. With temperatures lingering in the low-70s low- level lapse rates will steepen and windy conditions (gusts near 30-35mph) will occur quickly after sunrise. By late morning, mid- level dry is anticipated to quickly advance into Western PA prior to the passage of a cold front. In the wake of the cold front, a tight pressure gradient is expected to linger. Gusts up to 35 mph may continue across the region (40 mph in the ridges) tonight and early tomorrow morning.
1025 AM EDT Fri Mar 20 2020 Another warm/hot early Spring day is in store as high pressure remains in control. Surface and upper level ridging will remain in place across the area today. A frontal boundary will approach from the west, but the ridging is expected to keep the chance of rain west of the forecast area today.
301 AM MDT Fri Mar 20 2020 Snow showers are coming to an end this morning over most of the High Plains and adjacent high terrain, with just a few lingering snow showers along and south of the I-80 corridor. Warm air advection is keeping low hanging clouds and patchy to dense fog across much of the I-80 corridor as well, with a Freezing Fog Advisory issued earlier this morning for the I-80 Summit and along 287 south of Laramie. Upslope flow due to northerly and northeasterly winds is also contributing to the low level moisture and fog development.
604 AM CDT Fri Mar 20 2020 As of 3AM, a cold front has moved through the area with strong cold advection and gusty winds behind the front. As cold high pressure builds into the northern Plains, we'll see persistent northerly winds. With the north winds and cloud cover, we should only be able to climb into the mid 30s in our north to the low to mid 40s in our south.
There will be a sunny start to the Spring with sunshine supporting afternoon temperatures in the lower to mid 60s this afternoon.
High pressure will build into the area through the weekend with moderating temperatures and some sunshine. A rather complex weather system continues over the area with a large upper low centered near 44N/137W, a smaller low S of the main low and a third low over the CA/NV border. These 3 features reside in a much broader trough that extends from the N Rockies into the E Pacific. The 2 smaller lows will gradually be absorbed by the larger low over the next couple of days, with this low moving ESE toward the central or S CA coast by late in the weekend.
622 AM CDT Fri Mar 20 2020 1041 mb arctic high pressure centered over Saskatchewan will build through the Dakotas and north central Nebraska today. Elsewhere, highs in the lower 30s are in place. The arctic high pressure will move off east tonight with cold south winds developing. The arctic high pressure moves over the Great Lakes Saturday and spreads out at the same time. Thus, south winds will continue Saturday but a warm front should move at least part way through western Nebraska.
524 AM MDT Fri Mar 20 2020 Snow showers are coming to an end this morning over most of the High Plains and adjacent high terrain, with just a few lingering snow showers along and south of the I-80 corridor. Warm air advection is keeping low hanging clouds and patchy to dense fog across much of the I-80 corridor as well, with a Freezing Fog Advisory issued earlier this morning for the I-80 Summit and along 287 south of Laramie. Upslope flow due to northerly and northeasterly winds is also contributing to the low level moisture and fog development.
A cold front was located just north of the area early this morning, stretching from southeast Kansas into the west central Missouri. Ahead of the front, temps were generally in the lower 60s across the area with mostly clear skies. The cold front will sweep through the area this morning, therefore a non diurnal temperature range is expected today with temps falling and perhaps leveling off by afternoon into the 40's.

Strong thunderstorm activity is initiating in Central/Eastern Ohio with moisture convergence ahead of the cold front. 4 inches), and dewpoints in the low-60s will create impressive rainfall rates at times. With temperatures lingering in the low-70s low- level lapse rates will steepen and windy conditions (gusts near 30-35mph) will occur quickly after sunrise. By late morning, mid- level dry is anticipated to quickly advance into Western PA prior to the passage of a cold front. In the wake of the cold front, a tight pressure gradient is expected to linger. Gusts up to 35 mph may continue across the region (40 mph in the ridges) tonight and early tomorrow morning.
634 AM CDT Fri Mar 20 2020 Isolated showers will be possible this morning as a cold front pushes through central Illinois. 07z/2am surface analysis shows a cold front extending from southern Lake Michigan across north-central Illinois into central Missouri. Early morning highs will range from the lower 40s in the Illinois River Valley to the lower 60s south of I-70. with readings falling into the lower to middle 40s across the board by this afternoon. Canadian high pressure will build into the Upper Midwest tonight, resulting in clearing skies and winds diminishing to less than 10mph overnight. Cool/dry weather will be on tap for Saturday with well below normal high temperatures in the lower to middle 40s.
However, will expect the an increase in rain chances once again Saturday due to an increase in isentropic lift and convergence between remnants of the cold front and a developing coastal trough. With the current timing of the front and current morning activity, inland locations generally west of Highway 59 may have a tough time warming up which would leave temperatures in the low to mid 70s.
140 PM EDT Fri Mar 20 2020 Clearing and cold tonight as high pressure builds in across the Great Lakes. However continued unsettled as next srn stream disturbance ejects northeast ahead of reloading wrn CONUS mean trough late Tue with rain overspreading the area once again. Vigorous sfc cyclone track up through wrn OH likely to yield some decent rainfall totals once again.
1214 PM CDT Fri Mar 20 2020 As of 3AM, a cold front has moved through the area with strong cold advection and gusty winds behind the front. As cold high pressure builds into the northern Plains, we'll see persistent northerly winds. With the north winds and cloud cover, we should only be able to climb into the mid 30s in our north to the low to mid 40s in our south.
246 PM MDT Fri Mar 20 2020 20z surface analysis had high over northwest MN and warm front across central MT into CO.
Clouds will likely fill back for a brief period coincident with evening stabilization, but more aggressive erosion of clouds downstream of Lake Superior is already underway in response to 1040mb high pressure over North Dakota building eastward.
326 PM CDT Fri Mar 20 2020 Much cooler temperatures today versus 24 hrs ago as strong cold air advection overspread the region behind the cold front.
1224 PM CDT Fri Mar 20 2020 Temps have finally warmed into the lower tends, though a few locations have still be slow to exceed the single digits. Winds have slowly decreased overnight and will continue to do so this morning as high pressure moves into the area.
Cloud cover will be pretty decent, and as a result the temperatures will still be on the cool side, with highs in the low 50s.
In the wake of a cold frontal passage earlier today, strong cold advection will bring a cold night to central Indiana. Cooler than normal temperatures will continue through the weekend.
A vigorous line of convection ahead of a cold front will move through NY and PA this afternoon, mainly between 2 PM and 7 PM. However, shear is very high, especially through the lower atmosphere.
Front will enter the CWA overnight then quickly wash out as ridging briefly reasserts itself on Saturday.
A cold front is moving southeast through the area with patchy MVFR ceilings and an area of rain with occasional embedded storms. /issued 921 AM CDT Fri Mar 20 2020/ Have updated pops over the lakes region of southeast Texas and central Louisiana thru the day today has a cold front approaches from the west. /issued 635 AM CDT Fri Mar 20 2020/ MVFR conditions are expected through most of the forecast period as a cold front slowly moves through the area. Elsewhere, a cold front moving through OK/N TX will be moving through the region later today. Temperatures this morning are still ridiculously in the lower to mid 70s, some 20+ degrees above normal. The wind pattern aloft is primarily influenced by the large mid/upper level trof over the Western U.
High pressure ridge axis concentrated (east-west) across the central FL peninsula and points further into the western Atlc. Aloft, high pressure over the southern Gulf continues to retrograde westward. High pressure aloft centered over the southwest GOMEX will build back eastward towards the southwest FL coast as pressure heights increase and flow becomes zonal again. At the surface, east- west ridging over the south-central peninsula will get pushed south/east through mid-week, then build back into the area Thu night- Fri. Warm and mainly dry conditions continue, as high pressure persists over the area. Ridge axis over the central peninsula will slide a bit south into south-central FL by late in the period.
The low level winds will soon begin to veer to NE for Saturday with more rain returning by sunset, if not a little before over other southern tier of Co/Pa. This will go with IFR/MVFR tempoed back and then a normal progression of lifting cigs with deepening cooler and drier air.
The high slides east late tonight, with southerly flow returning to the area on Saturday. This will allow warmer air to be pulled up into the region, with high temperatures ranging from the mid 30s east to the mid 40s west Saturday afternoon.
The morning maps showed low pressure over the Great Lakes with a trailing cold front down to the Mo Bootheel. The latest NAM shows lighter some shower activity lingering well into the night behind the cold front. A cold front will work slowly across the terminals today with scattered showers ahead of it.
