902 PM CST Wed Feb 8 2017 Pressure gradient continues to slowly slacken across the area in the cold front that finally has pushed through the state. Winds will be out of the north at all locations as the cold front continues to move through the southern portions of the state. The weak cold front continues to make progress slowly moving south over AR, and was from TXK to south of LIT to east around MEM. Clouds had cleared, and behind the front, drier and cooler air, and a northwest to northeast surface wind flow was noted. Aloft, the upper low pressure through continues to push east taking the storm system with it.
A high pressure system will move across Indiana from the west overnight.
911 PM EST Wed Feb 8 2017 The cold front, which hasn't even reached northern Georgia yet, will accelerate southeastward overnight and move through our area late tonight into early Thursday morning. The cold front will arrive with a few additional showers late tonight to around sunrise. Noticeably cooler and drier air will dive into the region on Thursday with skies quickly clearing by mid to late morning. Southwest winds will become gusty after midnight and then veer to the northwest and increase even further Thursday morning behind the cold front.
I have adjusted lows a few degrees cooler than models are outputting as feel models are not taking into account recent snowfall across north central and the northern Sandhills from last night. Across southwest Nebraska have kept temperatures in the teens as this area does not have snow covered ground and felt they would stay slightly warmer.
Colder air will turn any lingering rain showers to snow showers over the higher elevations overnight, and some snow showers may even mix in across the valley areas late tonight.

549 PM CST Wed Feb 8 2017 Today's cold front has pushed through all of North Texas and was nearing the Upper TX Coast late this afternoon. /ISSUED 256 PM CST Wed Feb 8 2017/ The cold front blew through North TX today with some gusty winds and cooler temperatures.
Any snow should be short lived and with temps above freezing, do not expect any accumulations. For the rest of the afternoon, expect rain showers to increase over the area and continue through much of the evening hours courtesy of an upper level trough and cold front passing through the region. With temps above freezing before midnight and antecedent warm grounds, don't anticipate any impacts. Thu night looks dry with high pressure in place.
/Issued 344 PM CST Wed Feb 8 2017/ Cold front this afternoon has pushed south of the area.
Dry high pressure was located over the Dakotas this afternoon. The high will be in the vicinity of the region tonight and the sky should remain fairly cloud free.
A cold front moving through the area currently will shift winds from the northeast, which will then gradually veer around from the southeast through the remainder of the TAF period. /issued 241 PM CST Wed Feb 8 2017/ Temperatures have warmed into the lower to middle 70s across much of the area this afternoon, some 15 to 20 degrees above normal for this time of year. The only factor limiting our high temperatures today will be a northerly wind shift later this afternoon, a precursor to an approaching backdoor cold front. The backdoor cold front is expected to make its way into the area later this afternoon and into the evening hours. No rain is expected with this cold front, with temperatures expected to fall into the 30s tonight.
540 PM EST Wed Feb 8 2017 A strong cold front will move through the region tonight.
/issued 242 PM CST Wed Feb 8 2017/ Cold air has poured into the region following last nights cold front. When you add in fairly gusty winds, fire weather concerns will be elevated over this period, especially across the warmer and drier western parts of the CWA.
A cold front will swing though early in the period.
950 PM CST Wed Feb 8 2017 Wx map show cold front through inland Southeast Texas and Central Louisiana. Cold front just northwest of LFK late this afternoon. Wind expected to shift to the N overnight, then NE after daybreak as the high quickly moves north and east of the region through Thursday. /issued 341 PM CST Wed Feb 8 2017/ A cold front is bisecting the state from roughly Alexandria to Jasper, TX at this hour. The front, which is not expected to produce much more than just broken cloud cover, will continue to sink to the south this evening and tonight ushering in cooler and drier air for Thursday.
For the rest of the afternoon, expect rain showers to increase over the area and continue through much of the evening hours courtesy of an upper level trough and cold front passing through the region. With temps above freezing before midnight and antecedent warm grounds, don't anticipate any impacts. Thu night looks dry with high pressure in place.
Snow showers will continue through Thursday night before tapering down as high pressure builds over the region. Warmer conditions are expected over the weekend. Inversions should lower late Thursday and high pressure building in will help diminish snow showers. High pressure will begin to edge in from the west, tapering down additional snow showers. Snow may linger longer in the high terrain and across areas north of I-80, but additional accumulation shouldn't be significant.
A secondary front will move across the area Thursday morning, and should clear out the fog and most of the low ceilings from north to south between 10-16z, although some lingering MVFR ceilings will be possible behind the front into the afternoon. Increasing S-SW flow this evening and tonight to produce moisture pooling of warm dewpoint airmass over cool shelf waters ahead of an approaching cold front creating areas of dense sea fog, mainly from the Tampa Bay area northward through Cedar Key. Strong and fast moving vort lobe to push isolated-scattered showers through the NE Gulf and Nature Coast overnight around C FL by daybreak to SW FL after sunrise, well ahead of the cold front. By Thursday afternoon NW flow aloft brings a cooler and drier seasonal airmass into the region on breezy NW-N winds.
This may cause min temps to be a couple degrees warmer than previously forecast. High pressure over the northern and central plains with low pressure over the east coast of the U.
Tomorrow, after a bitterly cold start, strong warm air advection kicks in as a low pressure center develops over Alberta and southerly winds pick up.
1026 PM EST Wed Feb 8 2017 A strong cold front will move through the region tonight.
Cold front just northwest of LFK late this afternoon. Wind expected to shift to the N overnight, then NE after daybreak as the high quickly moves north and east of the region through Thursday. /issued 341 PM CST Wed Feb 8 2017/ A cold front is bisecting the state from roughly Alexandria to Jasper, TX at this hour. The front, which is not expected to produce much more than just broken cloud cover, will continue to sink to the south this evening and tonight ushering in cooler and drier air for Thursday.
828 PM CST Wed Feb 8 2017 At 8 PM the cold front was located just south of a Rockprings to Hondo to Gonzales line. /ISSUED 516 PM CST Wed Feb 8 2017/ /00Z TAFS/ A weak cold front cleared the Hill Country around 4 PM and now it is pushing across parts of the escarpment. Gusty winds of 15 to 25 mph are expected this evening into the overnight hours as the dry and cooler airmass moves to the south. The cold front is progressing through the area and should be all the way through by 6 pm. Much cooler and drier air will move into the area overnight, bringing a substantial change in temperatures back to near seasonal normals by tomorrow morning.
607 PM EST Wed Feb 8 2017 Snow will end from west to east into this evening as low pressure departs.
643 PM EST Wed Feb 8 2017 A low pressure area will develop off the mid Atlantic coast overnight. This low pressure area will move northeast and intensify rapidly on Thursday. A low pressure area will develop off the mid Atlantic coast late tonight and then move rapidly northeast and intensify and will be south of Cape Cod by early Thursday afternoon.
407 PM CST Wed Feb 8 2017 A cold front continues to make progress south and east across the area and was located roughly from north of KTYR, to north of KTXK, to between KMEZ and KMWT. The leading edge of the northwest winds is actually due to a pre-frontal trough. Northwest flow will usher cold air back into the region tonight, and subfreezing temperatures are likely in SE OK/SW AR.
516 PM CST Wed Feb 8 2017 /00Z TAFS/ A weak cold front cleared the Hill Country around 4 PM and now it is pushing across parts of the escarpment. Gusty winds of 15 to 25 mph are expected this evening into the overnight hours as the dry and cooler airmass moves to the south. The cold front is progressing through the area and should be all the way through by 6 pm. Much cooler and drier air will move into the area overnight, bringing a substantial change in temperatures back to near seasonal normals by tomorrow morning.
Upper level ridging will make it warmer for Thursday, but I increased wind speeds a bit Thursday, peaking out the sustained winds at 16 to 18 kts from the south just ahead of the approaching warm front, so although temperatures will warm up to the mid 30s to mid 40s, the wind will keep a bite in the air.
A cold front will move through the area this evening, bringing northerly winds and drier air into the region. Overnight lows will be in the low/mid 50s inland and upper 50s along the immediate coast. Despite some slightly cooler air across the region, afternoon highs will still be above normal on Thursday with temps in the lower to middle 70s. Northeast winds will increase behind a cold front tonight.
Some storms will fire up along and ahead of the cold front as it drops across the area this evening. The tornado potential is non zero, but 0-1 km storm relative helicity is a little on the low side. Atmospheric moisture thins out rapidly as the cooler air moves in from the northwest and by late tonight and early Thursday, most of the moisture is confined to the 1000-850mb layer. There is a slight chance for some patchy freezing drizzle for a few hours around sunrise along the Cumberland Plateau, before precip cuts off entirely after 13z. However, since ground temperatures are so warm and any freezing precipitation that falls will be very light, do not expect any travel problems.
High pressure will build into the region through Thursday.
High pressure will bring mainly dry conditions and mild temperatures to much of the area through Thursday.
Ridge axis was in place west of the region over Idaho, and west/northwest flow aloft was over the region. Entrenched within this upper level flow was a stream of Pacific moisture and much warmer temperatures.
As a cold front moves farther east tonight, winds will diminish. /issued 339 PM CST Wed Feb 8 2017/ (Tonight and Thursday) As of 2 PM, a NW-SE oriented pre-frontal trough/wind shift with modest cooling was south of I-20, making its way through the Concho Valley. Temperatures tonight will be quite a bit colder behind the front tonight for lows, dropping into the lower 30s north of I-20 to near 40 for the I-10 corridor. Cooler temperatures will continue for Thursday, although we will still be above normal in most areas.
645 PM EST Wed Feb 8 2017 A strong cold front will move through the region tonight.
Much warmer temperatures are expected the next couple of days with some locations likely to break record highs.
Cold air advection accompanying the low stratus continues to steadily keep temperatures below freezing this afternoon across northeast Kansas. An upper trough passing over the Great Lakes Region towards Thursday morning will increase high clouds from northwest to southeast. Highs Wednesday are slightly warmer given the sunshine with readings in the mid to upper 30s.
928 PM EST Wed Feb 8 2017 Snow will end from west to east into this evening as low pressure departs.
An area of high pressure, currently over the region, will bring cold temperatures tonight with lows in the single digits below and low teens below zero.
Temperatures were struggling to reach 30 at Hays at mid afternoon and only in the low 40s at Elkhart. By midday Thursday the upper trough will be sliding farther east while upper level ridging over the Rockies builds eastward toward the Plains. Return southerly flow will develop over western Kansas tonight as the high moves east and lee side troughing develops along the eastern slopes of the Rockies. There could also be quite a gradient in temperatures as the retreating high pressure will keep high temperatures confined to the upper 40s/around 50 over central and south central Kansas. Highs could reach 70 or the lower 70s over the far southwest where warmer air will be advecting in.
The low temperatures tonight should rapidly fall after sunset with relatively clear skies and fresh snow cover most areas. Utilized the coldest guidance among models to initialize the minimum temperatures then tweaked the lows for anticipated cloud cover (southwest) which will be rather sparse tonight. Still expecting some mixed precipitation in the form of sleet, freezing rain and snow across the far west central and north in the afternoon and evening hours.
805 PM EST Wed Feb 8 2017 A strong cold front will move through the region tonight.
The clear skies and light winds within the ridge axis will allow for overnight lows a few degrees either side of zero tonight, coolest across our far north, as well as over the fresh snow cover near the Missouri River Valley. Much of the warming aloft will not yet be realized at the surface, with highs on Thursday expected to hold in the lower-mid 20s for most areas.
823 PM CST Wed Feb 8 2017 The cold front has now cleared the CWA with gusty north winds observed across all of the Mid-South. The marginally severe convection along the cold front has moved off to the east with dry conditions anticipated for the remainder of the night. /issued 317 PM CST Wed Feb 8 2017/ Windy and colder conditions will arrive to the Midsouth this evening, behind a strong cold front passage. upper level trof lifts out to the Atlantic and upper level ridging builds over the plain.
We trended temperatures slightly cooler tonight given the stronger push of the cold front today. Temperatures will be cooler Thursday, but will recover quite a bit by afternoon on the caprock.
Winds will be out of the north at all locations as the cold front continues to move through the southern portions of the state. The weak cold front continues to make progress slowly moving south over AR, and was from TXK to south of LIT to east around MEM. Clouds had cleared, and behind the front, drier and cooler air, and a northwest to northeast surface wind flow was noted. Aloft, the upper low pressure through continues to push east taking the storm system with it.
Skies are mostly sunny across the Northern Plains with mid and high clouds beginning to spill over the ridge into western portions of the forecast area. At the surface, arctic high pressure center has shifted into eastern SD with light southerly return flow beginning across western areas. Higher elevations of Northeast Wyoming and the Black Hills will slowly drop into the teens, then level off or even rise a few degrees overnight as warmer air starts to move in aloft. Upper ridge will shift eastward over the region, and a warm front will push into the area from the southwest.
temperatures should continue to fall through the overnight hours into the low to mid 30s for most areas. Dunn /ISSUED 549 PM CST Wed Feb 8 2017/ Today's cold front has pushed through all of North Texas and was nearing the Upper TX Coast late this afternoon. /ISSUED 256 PM CST Wed Feb 8 2017/ The cold front blew through North TX today with some gusty winds and cooler temperatures.
Amounts will be light and the chances for measurable precip will be on the low side. Across that plateau area it looks as though freezing levels will drop down to around 2500 ft msl around 09z. Sfc temps across the Plateau wont likely get below freezing until around sunrise.
538 PM CST Wed Feb 8 2017 High pressure building behind a cold front will maintain NW winds around 15 knots with higher gusts through 09/04Z across area terminals. /issued 407 PM CST Wed Feb 8 2017/ A cold front continues to make progress south and east across the area and was located roughly from north of KTYR, to north of KTXK, to between KMEZ and KMWT. The leading edge of the northwest winds is actually due to a pre-frontal trough. Northwest flow will usher cold air back into the region tonight, and subfreezing temperatures are likely in SE OK/SW AR.
555 PM CST Wed Feb 8 2017 The short wave trof currently centered in middle MO is moving east- southeast at a steady pace. Current indications are the short wave trof will be exiting the CWA at 00Z. We should see gradual northeastward clearing of the stratus this evening into the overnight hours, however some high clouds in the northwest flow aloft will be spreading into the area in the wake of the low clouds. Impressive cold air advection will bring rather chilly air into the region tonight as high pressure builds southeastward, with most locations seeing lows well into the teens. The combination of the cold high pressure system and clouds will result in a rather cold day, with highs on Thursday anywhere from 10-15 degrees below average.
/issued 317 PM CST Wed Feb 8 2017/ Windy and colder conditions will arrive to the Midsouth this evening, behind a strong cold front passage. upper level trof lifts out to the Atlantic and upper level ridging builds over the plain.

Temperatures have remained generally steady in the mid/upper 20s and will begin to fall later this afternoon and continue falling into the lower/mid teens by Thursday morning. cms 327 PM CST High pressure to build across the region on Thursday with dry weather expected across the area. However, after another chilly night Thursday, warmer weather will spread back north across the region in advance of low pressure over the Plains and stronger southerly winds.
Cold front across the southeast U. Added LLWS to the TAFs north of KSUA, as models have increasing low level jet of 35-40 kts extending across the area overnight into early morning Thursday, ahead of an approaching cold front.
a cold front will move through the region. /issued 345 PM CST Wed Feb 8 2017/ SHORT TERM (Tonight through Thursday Night): Temperatures are once again setting records across the Rio Grande Valley as surface winds continue to veer to the southwest this afternoon, allowing for another day of intense heating off the high terrain of Mexico. Tonight, a deepening low pressure system will move across the Ohio Valley and into the mid-Atlantic with a trailing cold front moving southward into Deep South Texas. 12Z model guidance is trending cooler on temperatures for Thursday morning and afternoon with drier air than expected to move through.
Temperatures this afternoon to climb into the mid 90s areawide with dewpoint values forecast to fall into the low to mid 60s.
1204 PM EDT THU JUN 30 2016 High pressure is overhead today. A cold front will move east across the state on Friday followed by another high pressure area which will cover the region for most of the holiday weekend.
724 AM EDT THU JUN 30 2016 A ridge of high pressure will remain in firm control of the weather of eastern Kentucky today and most of the day on Friday. Highs today and tomorrow are forecast to top out in the mid to upper 80s, with overnight lows ranging from the upper 50s in valleys to the lower 60s elsewhere.
High pressure will provide another mild and pleasant day across central Indiana today. This frontal zone will stall to our south early in the weekend before returning back northward late in the weekend as low pressure develops and moves slowly east out of the south central Plains. A surface chart indicated a ridge of high pressure was across our region. This ridge will slide east later today and a light southwest flow develop across our area. The only changes with this update will be to slow down arrival of clouds a little and to tweak temperatures up slightly some areas as they are a few degrees warmer than this time yesterday and there will be weak warm advection later today.
At the surface, strong cold front stretches from northern MN through southern ND. Meanwhile, high pressure is centered over the Ohio/Tennessee Valley. Confidence is high that storms will either develop out over the high Plains late this afternoon and move into the forecast area tonight or storms will develop on the low level jet this evening over west-central KS.
Late afternoon/early evening the focus shifts toward an approaching cold front from the northwest which should arrive at the Galesburg area around 7 p. Highs today should increase to the low 80s across most of central IL as southerly flow develops behind the departing high pressure and approaching cold front. Most of the high- resolution models develop a line of showers and thunderstorms over Iowa and southern Wisconsin later this afternoon, moving across the northern half of the state this evening before fading out. Have consequently focused the highest PoP's from about I-55 westward this evening, and mainly around 30-40% PoP's after midnight to the east. A short period of dry conditions is then on tap as high pressure drifts across the Midwest.
/issued 418 AM EDT THU JUN 30 2016/ Southwest flow will prevail over the next few days as a trough persists across the panhandle and south GA/AL keeping our area in a muggy, unstable airmass into the weekend. The synoptic pattern will be dominated by stacked ridging aloft. and the lower level subtropical ridge axis extending across either the central or south-central Florida peninsula. Temperatures will be average to slightly above average due to the general ridging aloft. The close proximity of the subtropical ridge axis will keep synoptic winds and seas low. High pressure will dominate the area throughout the remaining work week and into the holiday weekend. As the high pressure moves closer to the Bay Area, afternoon surface coastal winds will shift from south-southwest to a west-southwest flow.
1237 PM EDT THU JUN 30 2016 High pressure centered over the area today will shift to the east coast on Friday. This will allow a cold front to sag south across the area tomorrow.
This feature combined with a cold front entering NE MO and WC IL and a prefrontal N/S trof oriented through eastern MO should generate additional scattered storms this afternoon. Confidence increasing in prolonged heavy rainfall and flood The aforementioned cold front will advance southward through the CWA tonight moving into southern MO and southern IL by daybreak Friday.
/issued 352 AM CDT THU JUN 30 2016/ (Today and Tonight) Upper ridging over New Mexico will continue to build southeastward into West Central Texas today and tonight. Temperatures will climb a degree or two from yesterday, to highs in the 92 to 96 range, with lows in the lower 70s tonight.
