and Thursday An arctic cold front tracking through northeast Wisconsin early this morning will usher in a cooler airmass across the region. Highs today will be cooler, ranging from the lower to middle 20s across the north, with highs in the lower 30s across east-central Wisconsin and the lakeshore. High pressure building in across the upper Mississippi Valley tonight will bring light winds and clearing skies later tonight. The aforementioned ridge of high pressure will track east over the Great Lakes region on Thursday; however, a low pressure system tracking well to the south could bring in some clouds to the area later on Thursday.
358 AM CST Wed Mar 9 2022 A broad long wave trof remains centered across western NOAM. Meanwhile a weak cold front now stretching through eastern IA will move across the area today. Even with the cold fropa, temperatures are expected to be warmer today owing to lots of sunshine as another big increase in clouds is not expected until later this afternoon.
535 AM CST Wed Mar 9 2022 A broad long wave trof remains centered across western NOAM. Meanwhile a weak cold front now stretching through eastern IA will move across the area today. Even with the cold fropa, temperatures are expected to be warmer today owing to lots of sunshine as another big increase in clouds is not expected until later this afternoon.
420 AM EST Wed Mar 9 2022 Rain and snow is expected today with a crossing trough.
On Thursday a trough moving in from the north may generate a few showers.
However, HREF and soundings suggests some higher clouds filtering in overnight which could keep temps slightly warmer in spots. Temps are only expected to climb into the 20s during the day Thursday as the high slide southeastward and weakens in between two areas of low pressure. Meanwhile snowfall trends with the Thursday evening system developing along the departed cold front's baroclinic zone continues to trend south with only a few hi-res models suggesting portions of southeastern WI getting clipped by any of its snow.
1118 AM CST Wed Mar 9 2022 (The rest of today ) High pressure centered overhead will result in a light wind regime across the forecast area today.
Confluent surface flow out ahead of the cold front will result in breezy southerly flow through the evening hours until the cold front approaches our northern zones in the southern Texas Panhandle after midnight. Did cool high temperatures slightly from NBM but still expect a diurnal pattern in tomorrows high temperatures until deeper moisture and cooler reinforced air arrives later tomorrow evening.
An upper level trough over Manitoba will progress eastward opening the door for an Arctic cold front to push into the area late Thursday afternoon into the evening. The aforementioned cold front is going act as the lifting mechanism, increasing snow chances across the region Thursday evening.
1151 AM CST Wed Mar 9 2022 (Today and tonight) Clear skies and relatively light winds have allowed temperatures to drop into the 20s and lower 30s across the area, with lows still expected to fall into the low to mid 20s, so we'll have a cold start to the day today. However, we will see warmer conditions today and tonight across the entire area. A weak upper trough will move through the southern plains today, inducing pressure falls along the lee slopes of the Rockies, which will increase our winds out of the south and southeast. Could also see a few highs clouds associated with the trough. Lows tonight will range from the low 30s in some of our valley locations to near 40 degrees in higher elevations where winds stay stronger, and the lower atmosphere remains more mixed.
Worth noting that short term ensemble guidance is advertising a jet streak around the back side of the exiting trough Thursday afternoon/evening, which would cause some localized enhancement of lift over southeast MT.
218 PM CST Wed Mar 9 2022 Rain/drizzle from early this morning now well south/east, as is an associated weak SFC/LL trough axis.
The leading edge of a cold front which slipped into the eastern OK Panhandle this morning has retreated north a bit but is still lurking nearby, very close the KS/OK state line. As the cold front begins to head back south, there may be enough couple lift to generate some really light showers, or perhaps drizzle/freezing drizzle across the OK Panhandle, but deep moisture appears to be lacking for any accumulating precip. The low stratus may thin and break up to some extent Thursday afternoon, but mid-level cloud cover should maintain mostly cloudy skies. Although there could be short period of mixed-phase precip early in the evening, the column should cool below freezing pretty quickly and it looks like this will be mainly a snow event.
(Through tonight ) Quiet weather expected overnight with a low chance of light showers across NE OK in proximity to strengthening cold frontal zone.
The region will be between high pressure to the east southeast and a frontal boundary to the northwest today.
Partial clearing this afternoon may allow for limited heating allowing temperatures to climb into the lower to middle 50s except for the highest plateau areas.
Gusty winds are possible in the Kern County Deserts from early Thursday morning until the late afternoon following the passage of a cold front. Dry weather and warmer than normal temperatures are expected over the weekend. A strengthening upper ridge off the CA coast has provided for mainly clear skies along with a slight warming trend today as temperatures are currently running 2-3 Deg F above yday at most locations in our area. This system will bring cooler temperatures to our area as well as bring a period of increased winds as a result of strengthening p-grads to the Kern County Desert areas where gusts up to 55 mph are possible. A few gusts exceeding 45 mph are also possible over the higher elevations of the Sierra Nevada on Thursday.
Temperatures this evening are expected to drop to near freezing for most of the area, with some places in northwestern OK getting into the low 20s. Precipitation is expected to start out as rain, but with the passage of a cold front by early Thursday morning, precipitation will transition into mostly snow. The aforementioned cold front is expected to make a push through central OK by the afternoon on Thursday, keeping high temperatures across the northern parts of the state in the upper 40s to lower 50s.
Expect temperatures on Thursday to be warmer than Wednesday's, with highs in the mid teens to low 20s.
Some clouds may bleed into southern MN as a low pressure system passes through the central CONUS. Thursday night lows will be a bit "warmer" in the single digits to lower teens as weak southwesterly flow occurs in advance of a Clipper system.
However, satellite imagery shows deeper clouds still spilling into the valley so suspect there will be some showers in the higher terrain through early this afternoon as northwest flow regime takes hold.

Thursday night we'll be watching a potent cold front dropping south through the CWA, with a fresh shot of arctic air.
119 PM MST Wed Mar 9 2022 Current surface map places high pressure across eastern Montana into western South Dakota. Brief warmup on Thursday ahead of next cold front.
1021 AM CST Wed Mar 9 2022 A cold front moves into the area today, turning winds to the northwest.
(The rest of today ) High pressure centered overhead will result in a light wind regime across the forecast area today.
257 PM EST Wed Mar 9 2022 Snow ends by early this evening, beginning a dry period of weather through much of the rest of the week as high pressure and warmer temperatures take hold across central PA.
The main weather story will be a powerful cold front progged to push through the island chain over the weekend.
A cold front approaches from the north tomorrow morning, reaching the northern Permian Basin by 15-16z.
(This evening through Thursday) Quiet weather will continue across West Central Texas the next 24 hours, although a cold front will enter northern portions of the Big Country tomorrow afternoon.
However, satellite imagery shows deeper clouds still spilling into the valley so suspect there will be some showers in the higher terrain through early this afternoon as northwest flow regime takes hold.

106 PM EST Wed Mar 9 2022 A cold front moves east across the area tonight, followed by high pressure on Thursday.
120 PM EST Wed Mar 9 2022 Rain tapers off this evening as low pressure moves east. High pressure for Thursday.
/Tonight through Thursday Night/ Cooler than normal conditions will quickly transition to near normal across the Ark-La-Tex as east-southeasterly winds linger ahead of the next frontal boundary. Until then, cloud cover finally breaks up overnight, allowing colder than normal minimum temperatures in the low-to-mid 30s.
1200 PM CST Wed Mar 9 2022 A cold front moves into the area today, turning winds to the northwest.
However, precipitation should remain well to our south in association with this wave, and closer to the low and mid level moisture transport.
524 PM CST Wed Mar 9 2022 (This evening through Thursday) Quiet weather will continue across West Central Texas the next 24 hours, although a cold front will enter northern portions of the Big Country tomorrow afternoon.
Tight gradient flow yields brisk north wind, with the highest gusts reserved for northwest Nye County and Tonopah. Daytime temperatures will be unseasonably cool with highs staying below freezing at some locations, like the snow covered northern valleys.
Freezing fog will also be possible in the valleys and basins tonight, if clouds are able to clear.
Current temperatures are in the low to mid 40s and already near dewpoint temperatures.
210 PM PST Wed Mar 9 2022 A trough of low pressure moving in from the north tonight combined with a strengthening Catalina Eddy over the coastal waters will deepen the marine layer and spread low clouds into the valleys by Thursday morning.
527 PM CST Wed Mar 9 2022 (Through tonight ) Quiet weather expected overnight with a low chance of light showers across NE OK in proximity to strengthening cold frontal zone.
404 PM MST Wed Mar 9 2022 Current surface map places high pressure across eastern Montana into western South Dakota. Brief warmup on Thursday ahead of next cold front.
Pattern/Forecast: Longwave troughing through much of the CONUS, with multiple waves moving through the larger-scale flow. Its associated cold front is currently crossing NE lower, with colder air filtering in behind it.
942 PM EST Wed Mar 9 2022 Low pressure will continue out to sea tonight.
Thursday night, an upper level trough will stretch from Ontario Canada southwestward across Colorado and into Baja Mexico. This trough will be split with most of the energy over the Upper Midwest and Southwestern Arizona.
A cold front will produce a brief northerly wind shift at HOB toward daybreak Thursday, before winds return to the S/SW by the afternoon. A cold front approaches from the north tomorrow morning, reaching the northern Permian Basin by 15-16z.
Muggy and mild as temps hover in the low 70s. Highs will remain well above normal in the low 80s across Lake and Volusia and mid to upper 80s farther south.
A cold front will move through the area early Thursday morning shifting winds to the north and becoming brisk. Confluent surface flow out ahead of the cold front will result in breezy southerly flow through the evening hours until the cold front approaches our northern zones in the southern Texas Panhandle after midnight. Did cool high temperatures slightly from NBM but still expect a diurnal pattern in tomorrows high temperatures until deeper moisture and cooler reinforced air arrives later tomorrow evening.
00Z TAFs VFR conditions will dominate the forecast tonight and Thursday as high pressure builds in. Despite it being warmer than yesterday, conditions remain rather cool across South Texas with temperatures ranging from near 60 degrees along the coast to near 70 degrees farther west across the Rio Grande Plains. High pressure and dry air has settled which, with light winds expected overnight, should lead to another chilly night with lows in the upper 30s inland to the mid to upper 40s farther south across the southern Brush Country and across the coastal region. Slightly warmer temperatures are expected with highs ranging from near 70 at the coast to the upper 70s across the Brush Country and Rio Grande Plains.
High pressure continues to dominate the area and will result in dry conditions through tomorrow.
BELOW ZERO TEMPERATURES ACROSS PORTIONS OF NORTHERN ROCKIES Relatively cold east/northeast winds will continue to be present across the Northern Rockies through this evening, as high pressure develops over the region.
651 PM EST Wed Mar 9 2022 Snow ends by early this evening, beginning a dry period of weather through much of the rest of the week as high pressure and warmer temperatures take hold across central PA.
It still looks like skies will turn mostly cloudy by daybreak as the the 500 mb trough slowly approaches from the west.
Have issued a Wind Chill Adzy through 15z Thursday w/ the exception of the southern NE Panhandle given potential for lingering clouds to help keep low temperatures just a bit "warmer" than areas to the north and west.
Northerly winds post frontal boundary have kept temperatures on the cooler side today and lows for tonight will drop to the low 40s to upper 30s. By Thursday morning, mid-level ridging will begin to build in and dry weather will rule across the region.
541 PM CST Wed Mar 9 2022 A longwave trough of low pressure was the main feature across the CONUS this morning. The axis of this main trough extended from central Manitoba, south southwest into northern Mexico. An arctic cold front will back into the forecast area on Thursday night.
Slightly warmer, but still much below average temperatures are expected tomorrow, with little in the way of precipitation.
Looking ahead, the most recently initialized suite of CAM guidance suggests a quicker time of arrival of the cold front moving from northwest to southeast across North Dakota tomorrow afternoon and evening. Several ingredients are present in the latest iteration of the RAP, including strong pressure rises and low level frontogenesis associated with the cold front, marginally sufficient low level RH, low level theta-e lapse rates near zero, and mean BL winds approaching 35 kts.
929 PM EST Wed Mar 9 2022 Weak lake-aggregate troughing remains over the Great Lakes region late this evening. Remaining weak troughing should gradually break down overnight as upstream ridging begins to poke into the Western Great Lakes. Pattern/Forecast: Longwave troughing through much of the CONUS, with multiple waves moving through the larger-scale flow. Its associated cold front is currently crossing NE lower, with colder air filtering in behind it.
Despite it being warmer than yesterday, conditions remain rather cool across South Texas with temperatures ranging from near 60 degrees along the coast to near 70 degrees farther west across the Rio Grande Plains. High pressure and dry air has settled which, with light winds expected overnight, should lead to another chilly night with lows in the upper 30s inland to the mid to upper 40s farther south across the southern Brush Country and across the coastal region. Slightly warmer temperatures are expected with highs ranging from near 70 at the coast to the upper 70s across the Brush Country and Rio Grande Plains.
Cold dry conditions accompanied by breezy ridgetop winds will then develop tonight into Thursday morning.
Rain/drizzle from early this morning now well south/east, as is an associated weak SFC/LL trough axis.
With clouds clearing out in the northeast overnight lows will drop further than tonight, even though the daytime high will be warmer tomorrow before the frontal arrival.
High pressure continues to dominate the area and will result in dry conditions through tomorrow. Expect unseasonably cold temperature during the overnight tonight, with areas of frost or fog possible Thursday morning in the lowlands.
Current temperatures are in the low to mid 40s and already near dewpoint temperatures. Highs should reach the lower to middle 60s and upper 60s to around 70 on Friday. A potent trough digs into the northern Plains and upper MS valley bringing a reinforcing Arctic front southeast with it. At the same time, a wave at the bottom portion of the trough in the intermountain west will dig into Desert Southwest and shear out as it phases loosely with the northern trough Friday night. At the surface, a low develops in the lower MS valley that moves northeast along the I-20/59 corridor as it deepens. This as the Arctic front drops southeast in advance of the strong upper trough. This is one of the more significant cold fronts to affect this area in March, along with a fairly rare March snowfall.
Northerly winds post frontal boundary have kept temperatures on the cooler side today and lows for tonight will drop to the low 40s to upper 30s. By Thursday morning, mid-level ridging will begin to build in and dry weather will rule across the region. Temperatures will be more seasonable tomorrow as a warming trend is expected ahead of another cold front late Friday. Temperatures will climb into the upper 60s to the low 70s.
Freezing fog will also be possible in the valleys and basins tonight, if clouds are able to clear. The area sits under the influence of a building ridge of high pressure, so temperatures moderate by the afternoon, but remain well below-average with weak mixing winds. Strong northwesterly jet flow around the ridge will support scattered snow showers in the northwestern Wyoming ranges, but accumulations will not be significant.
334 AM EST Thu Mar 10 2022 Discussion/Marine - Snow Threat Tonight into Friday - A shallow trough extending across the upper mid west will be behind some isentropic lift that should allow for bands of snowfall through southern Michigan.
1020 PM MST Wed Mar 9 2022 Current surface map places high pressure across eastern Montana into western South Dakota. Brief warmup on Thursday ahead of next cold front. Cold front slides through the area Friday night.
257 AM CST Thu Mar 10 2022 The cold front is pushing through the region ahead of schedule. The positively tilted upper trough currently over northern California should be approaching/over the Four Corners around midnight tonight. Lift from the trough will also begin to move into the region with snow developing first across the northern and central Texas Panhandle before moving into the extreme southern Panhandle before sunrise. A chance for freezing drizzle does remain between midnight and sunrise across much of the area, but there is decent uncertainty in the low levels moistening enough before mid/upper level lift moves over the region providing enough lift for snow. One thing working against freezing drizzle is surface winds will be out of the north as opposed to easterly upslope flow.
Main story remains the expected light snow event Friday night, associated with the passage of an open, neutrally-tilted longwave trof passage through the MS River valley. The northern branch trof passing through the MS River valley will be preceded by a surface cold frontal passage through the Midsouth Friday afternoon and early evening. Surface temps should cool to the lower and mid 30s by late Friday evening, as southern branch midlevel moisture lifts into the region, supporting widespread rain. As the column cools with the arrival the upper trof, a transition to snow is expected, perhaps including a brief period of sleet. Being an open trof, this system will have little to no TROWAL, basically wrap-around uplift of warm moisture that could supply moisture to the dendritic (-12C to -18C) growth zone.
and Friday High pressure will slide across the area today, bringing quiet weather to the area. Some mid and upper clouds will stream in at times from a low pressure system well to the south. The high will shift east tonight, as a clipper system approaches southwestern Ontario late tonight. Lows tonight will be a bit warmer; ranging from the single digits above zero across the north, with lows of 10 to 15 across east-central Wisconsin. The low will continue tracking through Ontario on Friday, bringing a cold front through the western Great Lakes region Friday morning. Given the limited moisture snowfall amounts will be very light, with the highest amounts across north-central Wisconsin where a dusting is possible.
1048 PM EST Wed Mar 9 2022 High pressure for Thursday and most of Friday brings dry and seasonable weather.
Around 02-04Z, a cold front will move into the region, resulting in gusty NE/E winds, particularly at HOB, INK, and MAF. A cold front approaches from the north tomorrow morning, reaching the northern Permian Basin by 15-16z.
Clouds and light snow showers will continue in and near the convergence zone and keep temperatures a little warmer than other areas that clear out. Wind chill early Thursday morning will dip to near 10 degrees in the Snake Basin, 5 below zero to 5 above in eastern Oregon and in the clearer valleys in western Idaho, but as low as 25 below zero in the higher eastern basins in Valley and Boise Counties. On Friday night warm-frontal clouds ahead of a Pacific upper ridge will moderate temperatures further, and begin a significant warming trend into the weekend.
KBYX is detecting a few showers accompanying this higher moisture in the Straits of Florida. High pressure over the Atlantic is currently maintaining moderate breezes across the coastal waters. Temperatures are still near 80 degrees across the island chain and dewpoints are in the lower 70s, which has made for a muggy night. Forecast soundings show an increase in moisture tonight, as well as the low-level inversion mixing out.
Temperatures will be quite cold overnight ranging from 5 below zero up near the Pine Ridge to 5 above further to the southeast. An arctic cold front will back into the forecast area on Thursday night. Temps will be cold on Friday under the influence of the arctic airmass as highs will range from the lower 20s in the northeast, to possibly freezing in the far southwest. A warm front will push across the forecast area Friday night with much warmer air working into the area for the weekend.
High pressure continues to build into Middle TEnnessee this evening with mainly high clouds blanketing the mid state.
NAM is hinting that the low clouds could get trapped under an inversion and stay cloudy for a while after sunrise, but it's the outlier with most other models scattering out the clouds.
