1212 PM CST Tue Feb 27 2024 - A cold front moving across the area today will bring strong northerly winds gusting to 40 to 50 mph. - Today's cold front will also bring a small chance (20-30%) for snow with most locations expected to see only a dusting (a trace to a couple tenths of an inch) of snowfall accumulation this afternoon and evening. With a cold front beginning to move across the forecast area this morning, winds are expected to become northerly and increase in speed by daybreak today. High pressure will quickly move back in over the region so temperatures will rebound quickly, starting with Wednesday when highs recover to the 40s.
-Enriquez MORNING DISCUSSION: Cold front has pushed through northeast Montana, with skies beginning to clear across the north, and winds slowly subsiding. Temperatures remain cold today as high pressure and upper trof moves across the region. Cold air will quickly be replaced on Wednesday with upper ridge moving across the western states.
Winds will largely be 15 to 25 mph with gusts to 30-35 mph, in the higher elevations of north Georgia, gusts could reach 45 mph. Deepening trough over the central CONUS will push a cold front through the state Wednesday.
Rapid warming to the low 70s is likely by the early afternoon and to around 80 in the red hills region â but the duration of heating will not be the same as yesterdays which led to new daily record highs. The warming will be cutoff as a cold front passes through the area, reaching Hays by noon and pushing though Garden City by around 2 pm and Dodge by 3 pm, with isallobaric pressure rises along the frontal boundary creating gusts commonly to 50 mph or more and patchy blowing dust.
A nearly ~6-8 mb pressure change stretching across the Lower Mississippi Valley is enabling sustained winds of 20-30 mph with gusts up to 50 mph in some areas. A Wind Advisory is currently in effect for most areas along and north of the Highway 84 corridor, while areas south remain in a "Limited" risk for strong winds. Temperatures are expected to remain well above normal, with highs in the lower to middle 80s. The cold front will begin reach the upper Delta area early Wednesday morning with a narrow band of gusty rain showers, but at this stage, thunder appears too unlikely to include in the forecast.
(This evening through Wednesday) The current surface map indicates a strong cold front across southwest to northeast Kansas moving quickly south(3 to 5 MB/3hr pressure rises behind front), with a dryline closer to home over the southeast part of our area.
High pressure will continue to ridge west from the Atlantic Ocean across the region through Wednesday with fair dry weather persisting.
140 PM MST Tue Feb 27 2024 An area of low pressure will cross the region Wednesday and Wednesday night and bring widespread showers with isolated thunderstorms, beginning in the afternoon hours.
1148 AM CST Tue Feb 27 2024 - Falling temperatures expected throughout the day behind a strong cold front. A strong cold front continues advancing southeast across the Dakotas and is expected to arrive in our far northern counties around 12z.
214 PM CST Tue Feb 27 2024 - Colder air surging into western Kansas tonight will drop temperatures well below freezing by daybreak Wednesday morning.
Strong high pressure over the western North Atlantic continues to dominate the area as the Keys remain on its western periphery. The western periphery of this high will continue to dominate the weather across the Keys for next day or two under east to southeasterly flow. Temperatures will largely remain steady state for mid-late week with highs near 80 and overnight lows in the lower 70s. A powerful low pressure system is expected to strengthen rapidly as it moves northeastward from the western Great Lakes area and into Ontario, Canada south of Hudson Bay tonight into Wednesday morning. Its associated cold front will continue to press southeastward stalling and then decaying as it approaches the northern Gulf of Mexico and southern Georgia/northern Florida.
Winds will shift to the northwest after a cold front makes passage late tonight and early Wednesday, with 30 mph or higher gusts still possible. A few discrete cells with tornado potential are possible this evening, then overnight it shifts more to a line of storms along and just ahead of the cold front, with damaging winds, large hail, and isolated tornado hazards. - Temperatures turn sharply colder after the cold front's passage.
Our next weather disturbance will be arriving to the Northern Rockies this evening, as a broad trough of low pressure moves inland. Moisture on the leading edge of the trough has origins from the central Pacific that will be pumping in precipitable waters of 150-200% of normal over the region. This first round of snow will total between 6 to 12 inches for elevations above 4000 feet in the lower Clark Fork Region and the Clearwater Mountains of north-central Idaho.
121 PM CST Tue Feb 27 2024 An upper trough will continue to drive a surface boundary into the ArkLaMiss region overnight into tomorrow. Highs tomorrow will range from the lower 60s to middle 70s.
(This evening through Wednesday) Fire weather concerns will continue through at least early evening for most locations, especially as a strong cold front moves through the area. A Wind Advisory will continue through midnight as strong northerly winds behind the cold front move through the area.
Tonight into tomorrow, a line of showers and a few thunderstorms is expected to develop along a cold front to our northwest, then sweep southeastward through the cwa in roughly the 09Z-17Z timeframe. Main story will be the dramatic temperature drop behind the cold front.
(Today and tonight) The upper level ridge will start to slide off to the east today and the thermal ridge will weaken slightly for this afternoon. As the ridge moves east our winds aloft will turn southwesterly, bringing in increased moisture at upper levels and increased cloud cover. The highest winds are expected in the western Big Country and Concho Valley. The strong downsloping west winds and the thermal ridge will allow temperatures to remain well above-normal, but the slight weakening in the ridge and increased cloud cover will allow for temperatures to be a bit cooler than yesterday. A cold front will approach the area late tonight, moving out of the area by the early to mid morning.
- Snow, mainly over the higher terrain and eastern plains, will be tapering off throughout the evening.
WV imagery indicates a southwest flow aloft prevailing across the Western High Plains downstream of an upper level trough of low pressure dipping southeast through the Great Basin.
- A warmup will occur beginning Wednesday under high pressure ahead of the next weather system.
- Warmer temperatures and quiet conditions return tomorrow and continue through the end of the work week. The sun is starting to peak back in over the lower elevations of western Colorado and eastern Utah this afternoon, in the wake of the strong cold front that marched through this morning. These ranges can expect another 1-3 inches, with up to 6 possible at the highest elevations and along favored northwest slope. The winds this afternoon have prevented temperatures from falling quite as far as anticipated in the wake of the strong cold front. On the upside, high pressure and warmer air aloft begins to move in tomorrow, bringing moderating high temperatures and sunny skies.
The highest chances (40-65%) are along and north of I-80, where confidence in the band persisting is greatest. After a cold start to the day on Wednesday, temperatures will climb into the 40s as a ridge begins to move over the area.
513 PM CST Tue Feb 27 2024 (This evening through Wednesday) The current surface map indicates a strong cold front across southwest to northeast Kansas moving quickly south(3 to 5 MB/3hr pressure rises behind front), with a dryline closer to home over the southeast part of our area.
618 PM CST Tue Feb 27 2024 (This evening through Wednesday) Fire weather concerns will continue through at least early evening for most locations, especially as a strong cold front moves through the area. A Wind Advisory will continue through midnight as strong northerly winds behind the cold front move through the area.
(The rest of tonight) The much anticipated cold front has made its way to just south of I-44 this evening and will continue to push southward through the night, likely clearing the forecast area a little after midnight. Another abnormally cold night is expected Wednesday night, with temps dipping below freezing in most locations.
513 PM CST Tue Feb 27 2024 - Colder air surging into western Kansas tonight will drop temperatures well below freezing by daybreak Wednesday morning.
- Strong gusty northwest winds will increase tonight after a cold front moves into the area. - Much colder temperatures will follow the cold frontal passage tonight, dropping into the 20s by morning. This will be around 50 degrees colder than this afternoon's highs, which have been in the lower to middle 70s. The area of convection in our southeast will likely continue into the night as the cold front approaches from the northwest and west. Tomorrow, winds will be on the decrease as the cold high pressure quickly pulls away from the area. Highs tomorrow will get above freezing, but only into the middle to upper 30s. The warmer temps also mean and return to southerly winds and likely some unsettled weather. The bigger issue in the TAFs will be the higher winds once the front comes through this evening.
545 PM CST Tue Feb 27 2024 A cold front will move across the Mid-South overnight into Wednesday morning.
Fairly benign wx is on tap today and Wed as zonal flow (or even weak ridging) takes hold.
A cold front will move across the Mid-South overnight into Wednesday morning.
545 PM CST Tue Feb 27 2024 (This evening through Wednesday Night) The promised cold front will be knocking on our northwestern doorstep tonight as it closes in on the ArkLaTex.
Temperatures will then begin to cool from northwest to southeast in the afternoon as a cold front associated with a passing upper trough north of the region sweeps through the area. A broken band of light to occasional moderate showers with embedded isolated afternoon thunderstorm will accompany the cold front, with the best chance of measurable rainfall occurring across our northern zones. Overnight lows will only drop in the lower to middle 60's, with highs in Wednesday reaching the mid 70s to lower 80s prior to the arrival of the cold front.
702 PM CST Tue Feb 27 2024 An upper trough will continue to drive a surface boundary into the ArkLaMiss region overnight into tomorrow. Highs tomorrow will range from the lower 60s to middle 70s.
Some high clouds will continue to stream across the area tonight and Wednesday with the low level southeast to south flow continuing to bring moderating temperatures and humidity.
Issued by National Weather Service Lubbock TX 1120 PM CST Tue Feb 27 2024 (This evening through Wednesday night) A cold front is currently barreling towards the OK Panhandle from the north and should be on the stateline in roughly an hour from this writing. Temperatures will be on the downward trend with overnight temperatures expected to drop well below freezing. However, with the lower Tds behind the front RH values are expected to drop into the teens once again.
1046 PM CST Tue Feb 27 2024 (The rest of tonight) The much anticipated cold front has made its way to just south of I-44 this evening and will continue to push southward through the night, likely clearing the forecast area a little after midnight. Another abnormally cold night is expected Wednesday night, with temps dipping below freezing in most locations.
945 PM CST Tue Feb 27 2024 The cold front has slowed down a bit, so have made some adjustments to the timing of the cold front and associated wind, temperature and dewpoint grids. Otherwise the basics of the forecast are on track with much colder air filtering into the area behind the front and freezing temperatures spreading across the northern two-thirds of the area overnight. (This evening through Wednesday) Fire weather concerns will continue through at least early evening for most locations, especially as a strong cold front moves through the area. A Wind Advisory will continue through midnight as strong northerly winds behind the cold front move through the area.
1139 PM CST Tue Feb 27 2024 A cold front will move across the Mid-South overnight into Wednesday morning.
A trough axis pivots through the area this morning. Closer to the surface, a cold front pushes through ushering in much colder air. As such, temperatures are falling and able to reach freezing temperatures this morning into the midday time frame for areas south of US-24. 5 inches is possible with the highest totals from Laporte to Berrien and Cass, MI counties.
255 AM EST Wed Feb 28 2024 A strong cold front will move through the region this afternoon and evening.
VFR ceilings return after sunrise as a cold front moves through the area by the late afternoon. Temperatures will then begin to cool from northwest to southeast in the afternoon as a cold front associated with a passing upper trough north of the region sweeps through the area. A broken band of light to occasional moderate showers with embedded isolated afternoon thunderstorm will accompany the cold front, with the best chance of measurable rainfall occurring across our northern zones. Overnight lows will only drop in the lower to middle 60's, with highs in Wednesday reaching the mid 70s to lower 80s prior to the arrival of the cold front.
While the first part of the overnight hours have been relatively quiet across our CWA, we're still expecting storm activity to ramp up in coverage early this morning as a strong cold front approaches from the northwest and capping around 800mb erodes. Forecast hodographs also exhibit strong low level shear and clockwise curving in the lowest 0. Temperatures will rapidly plummet behind the cold front this morning, dropping from 60s into 40s and 30s in a matter of hours. Winds will also begin to slacken as high pressure builds in from the west. This should help temps fall quite a bit, with morning lows tomorrow in the low to mid 20s for many locations.
The cloud cover will remain over the south through tonight so temperatures will struggle to drop below freezing there. Elsewhere, near to a few degrees below freezing can be expected.
255 AM EST Wed Feb 28 2024 - Cold front pushing through early this morning - Travel Impacts Today - Warming up over the Weekend - Cold front pushing through early this morning As of 230 am, the cold front stretched from Mount Pleasant, through Grand Rapids to just west of Kalamazoo. It was approaching the freezing mark already near Ludington. Bridges and overpasses will be the first to cool down and become icy.
325 AM EST Wed Feb 28 2024 Low pressure and a strong cold front will move east across the Great Lakes and Ohio Valley today, bringing showers, thunderstorms, and windy conditions. High pressure will build quickly east into the Ohio Valley tonight, resulting in clearing skies, drier air, and much colder temperatures.
The warming and moistening trend continues and temperatures are now in the lower 70s with dew points in the lower to mid 60s. As a result, only fields of stratocumulus are found mainly across the warmer Atlantic side waters. Deep layered ridging will dominate with a persistent and rather low subsidence inversion. A ridge reaching across Florida will maintain gentle to moderate east to southeasterly breezes on Keys waters through the overnight period.
A weak upper low will bring some rain and very high elevation snow showers to the White Mountains Wednesday night.
140 AM CST Wed Feb 28 2024 - The cold front has finished moving through central and s outheastern Illinois tonight, ending the severe risk. As we wave goodbye to the cold front, we welcome in MUCH colder temperatures than what we have been seeing over the previous days. With the strong winds following behind the cold front, wind chills are going to get into the single digits this morning.
1057 PM CST Tue Feb 27 2024 The cold front has slowed down a bit, so have made some adjustments to the timing of the cold front and associated wind, temperature and dewpoint grids. Otherwise the basics of the forecast are on track with much colder air filtering into the area behind the front and freezing temperatures spreading across the northern two-thirds of the area overnight. (This evening through Wednesday) Fire weather concerns will continue through at least early evening for most locations, especially as a strong cold front moves through the area. A Wind Advisory will continue through midnight as strong northerly winds behind the cold front move through the area.
1051 PM CST Tue Feb 27 2024 (This evening through Wednesday) The current surface map indicates a strong cold front across southwest to northeast Kansas moving quickly south(3 to 5 MB/3hr pressure rises behind front), with a dryline closer to home over the southeast part of our area.
- Temperatures turn sharply colder after the cold front's passage.
(Today through Thursday) Cold front currently stretches from the central Great Lakes back through eastern Texas. Have not realized the higher gusts overnight in most locales outside of the highest elevations.
640 AM EST Wed Feb 28 2024 - Cold front pushing through early this morning - Travel Impacts Today - Warming up over the Weekend - Cold front pushing through early this morning As of 230 am, the cold front stretched from Mount Pleasant, through Grand Rapids to just west of Kalamazoo. It was approaching the freezing mark already near Ludington. Bridges and overpasses will be the first to cool down and become icy.
532 AM CST Wed Feb 28 2024 - The cold front has finished moving through central and southeastern Illinois tonight, ending the severe risk. As we wave goodbye to the cold front, we welcome in MUCH colder temperatures than what we have been seeing over the previous days. With the strong winds following behind the cold front, wind chills are going to get into the single digits this morning.
523 AM CST Wed Feb 28 2024 (Today and tonight) Significantly cooler temperatures will move into the region today behind a cold front along with increasing chances of wintry precipitation by daybreak on Thursday morning. A southern stream trough currently moving onshore in northern Baja California is forecast to eject eastward across northern Mexico and the southwestern US today and tonight. There is good lift with this short wave trough but the amount of moisture available will be the limiting factor to precipitation accumulation.
533 AM CST Wed Feb 28 2024 (Today through Thursday night) For today, much lighter winds along with sharply cooler temperatures are anticipated in the wake of the most recent cold frontal passage.
547 AM CST Wed Feb 28 2024 Through tonight: A cold front now extends from roughly Paducah KY to Little Rock AR to Texarkana and continues to progress toward our region early this morning. Though the LLJ will begin to pull east of the area this morning, a sharp pressure gradient along the cold front and CAA in its wake will maintain fairly gusty conditions through the day.
An area of low pressure will cross the region Wednesday and Wednesday night and bring widespread showers with isolated thunderstorms, beginning in the afternoon hours.
Following this system, expect near freezing Valley temps and AM frost.
A weak cold front will make its way towards the area tonight into tomorrow.
(Today through Thursday night) For today, much lighter winds along with sharply cooler temperatures are anticipated in the wake of the most recent cold frontal passage.
644 AM EST Wed Feb 28 2024 Low pressure and a strong cold front will move east across the Great Lakes and Ohio Valley today, bringing showers, thunderstorms, and windy conditions. High pressure will build quickly east into the Ohio Valley tonight, resulting in clearing skies, drier air, and much colder temperatures. The high will persist over the region into Thursday with below normal temperatures expected. Cold front is reaching the eastern portion of the ILN area. Skies will be mostly clear tonight and sunny on Thursday thanks to 1035mb high pressure tracking across Kentucky.
96 (Today through Thursday) Cold front currently stretches from the central Great Lakes back through eastern Texas. Have not realized the higher gusts overnight in most locales outside of the highest elevations.
Winds today will turn more southerly and become breezy across South FL in response to a low pressure system pushing across the Great Lakes region. This will allow high temps to warm into the low to mid 80s under mostly sunny skies with some passing thin high clouds. Tonight into Thursday, a frontal boundary associated with the low pressure system will push across the Southeast US before stalling out over north-central FL. Despite this leading to an increase in atmospheric moisture, the mid-level ridge will remain over the area and prevent rainfall chances from rising above a slight chance (10-15%).
550 AM CST Wed Feb 28 2024 A Wind Advisory remains in effect areawide until 9AM today for strong winds associated with a cold front. Much cooler and dry conditions will prevail for the rest of today and tomorrow as strong high pressure builds in.
A trough axis pivots through the area this morning. Closer to the surface, a cold front pushes through ushering in much colder air. As such, temperatures are falling and able to reach freezing temperatures this morning into the midday time frame for areas south of US-24. 5 inches is possible with the highest totals from Laporte to Berrien and Cass, MI counties. High pressure and warming takes place allowing a rebound to around seasonable high temperatures for Thursday in the mid 30s to around 40 degrees. By this time, the gradient relaxes though, so despite some lingering mixing to around 925mb, the low level jet has relaxed allowing for weaker surface winds. Behind the high pressure system, a warm advection wing comes in.
A Wind Advisory remains in effect areawide until 9AM today for strong winds associated with a cold front. Much cooler and dry conditions will prevail for the rest of today and tomorrow as strong high pressure builds in.
448 AM CST Wed Feb 28 2024 (Today and tonight) Temperatures will be much cooler today behind the cold front, with highs dropping around 35 degrees from yesterday. The cold front has moved through the Concho Valley and is entering the Northwest Hill Country and Northern Edwards Plateau as of 3 AM. Wind chills will be near or below freezing for much of the Big Country this morning. An upper level low has developed near Baja California and will progress east towards West Central Texas throughout the day today. As it nears our area, lift ahead of the trough will increase our rain chances. Temperatures Thursday morning will be primarily in the mid 30s to near 40, but a few areas could drop near freezing.
Case in point, its near 70F right now across the MO bootheel and near freezing in Jefferson city MO. The cold front will reach Nashville around 7 am, and clear our Plateau around 10 am.
