/Issued 1221 AM CST Mon Feb 19 2024/ /Monday and Tuesday/ South flow has returned and will help nudge this morning's temperatures a few degrees warmer than yesterday. Most locations will start the day above freezing but still cold in the mid 30s. Only locations in the Brazos Valley and our eastern 1-2 rows of counties are forecast fall below freezing this morning. Mostly clear skies and dry air will allow temperatures to quickly rise above freezing by 8-9AM. This afternoon will be noticeably warmer with highs in the 60s to low 70s. A slug of warmer air just above the surface will overspread the region from the west, helping reinforce the radiation inversion. The warming trend will continue Tuesday, with most of the area climbing into the 70s with locations west of US-281 forecast to climb into the low 80s.
(Rest of Today) High pressure centered over the Southeast has resulted in a chilly start to the day under clear skies and light winds.
505 AM CST Mon Feb 19 2024 (Today and tonight) Warming trend continues today as lee trough brings southwest to west winds 5 to 15 mph. Highs will be in the lower to mid 70s, with the warmest temperatures in the Concho Valley. Overnight lows will be more mild, mainly in the lower 40s.
419 AM CST Mon Feb 19 2024 - Above normal temps through the middle of the week with highs ranging from the low 40s to 50s. Issued 418 AM CST Mon Feb 19 2024 Today through Tuesday: Synopsis/Mesoanalysis: Located on the back side of surface pressure ridging, light & variable surface winds prevail across the region early this morning. Surface ridging will continue to migrate east toward the Atlantic coast on Tuesday, with breezy southwest winds becoming established by the afternoon hours.
But, temps should only top out to near climatic normals, with highs in the low to mid 60s. Warmer conditions will continue tonight as freezing temps are only expected across portions of SE Oklahoma and adjacent SW Arkansas. Upper ridging will build into the region on Tuesday.
Temperatures will not be quite as cold tonight with most locations expected to remain above freezing.
Since this is the area that has been warmer the past few days (due to little or no snow remaining), it may keep highs from getting quite as warm today as they could. The main story is that the thermal gradient looks to remain a little cooler to the north and slightly warmer south.
532 AM CST Mon Feb 19 2024 (Today through Tuesday Night) An upper ridge located over the Rockies will move into the Plains tonight. The upper ridge remains over the Plains through Tuesday.
Black ice will once again become the main threat overnight and early in the morning Tuesday, as any wet roads will experience some icing with temperatures lowering to below freezing. These types of cold fronts this time of the year also typically bring strong gusty winds, so stay tuned to further updates to the forecast. Patchy freezing fog will be possible for KGPI and KMSO this morning, through 19/1500Z.
Across the northern Sandhills into north central Nebraska, and the eastern Panhandle kept temperatures in the 40s, where snowpack will keep temperatures cooler. For Tuesday, the upper level ridge builds in from the west and will expect most of the snow pack to be melted today, thus have kept widespread temperatures in the upper 50s to low 60s for Tuesday. The upper level ridge will be fully centered over the Central Plains on before a weak front begins to move east out of the Rockies into the High Plains late Wed.
(Today and tonight) Warming trend continues today as lee trough brings southwest to west winds 5 to 15 mph. Highs will be in the lower to mid 70s, with the warmest temperatures in the Concho Valley. Overnight lows will be more mild, mainly in the lower 40s.
524 AM CST Mon Feb 19 2024 (Today through Tuesday) Key Messages: - Quiet pleasant weather today, warmer Tuesday. A strong mid/upper level high pressure system centered over the Pacific to the southwest of Mexico will maintain a subsident northwest flow across S TX today leading to another mostly sunny day. Temperatures will be around 10 degrees warmer today with highs ranging from the mid 60s east to mid 70s west. The upper level high is progged to shift northeast across Mexico and closer to S TX by Tuesday which will lead to highs in the mid 80s across the Brush country. Lows tonight will also be warmer at 45-55 degrees.
This gradual drying trend is expected to continue through the morning hours today, with a few isolated showers possible as the low continues to push eastward. Overnight lows will range from the lower 40s around Lake Okeechobee to the upper 40s for southwest areas and lower 50s for southeast areas. Highs on Tuesday will be a bit warmer, in the lower 70s for most of the area.
Bonnette Previous Discussion: /Monday and Tuesday/ South flow has returned and will help nudge this morning's temperatures a few degrees warmer than yesterday. Most locations will start the day above freezing but still cold in the mid 30s. Only locations in the Brazos Valley and our eastern 1-2 rows of counties are forecast fall below freezing this morning. Mostly clear skies and dry air will allow temperatures to quickly rise above freezing by 8-9AM. This afternoon will be noticeably warmer with highs in the 60s to low 70s. A slug of warmer air just above the surface will overspread the region from the west, helping reinforce the radiation inversion. The warming trend will continue Tuesday, with most of the area climbing into the 70s with locations west of US-281 forecast to climb into the low 80s.
630 AM EST Mon Feb 19 2024 Partly to mostly cloudy skies today and Tuesday, with slightly below normal temps, as a pair of upper lows move over the region, but no precipitation is expected.
619 AM EST Mon Feb 19 2024 (Today and tonight) High pressure with a much drier airmass will build into the area today. This will result in mostly sunny skies, light winds, and afternoon high temperatures generally in the low to mid 60s. Overnight lows will generally range from the low to mid 30s with areas of frost, except for the panhandle coast which will stay slightly warmer. The official forecast favors a MOS blend across the Florida big bend outside of urban areas, which usually performs well in radiational cooling regimes by being cooler than the NBM. Tallahassee will likely see its typical warm bubble, with lows in the city in the upper 30s and lows at the airport around freezing.
Highs on Tuesday should trend warmer in the mid to upper 60s.
Today will begin a warming trend for this week as an upper-level ridge pushes over the southeast later today.
502 AM CST Mon Feb 19 2024 (Today through Tuesday) Fine conditions are expected through the period, with the BRO CWFA on the northern periphery of a 500 mb ridge of high pressure building north out of neighboring Mexico.
617 AM CST Mon Feb 19 2024 (Today) Tranquil weather across the Tennessee Valley region this morning, with high pressure prompting clear/calm conditions.
906 AM EST Mon Feb 19 2024 High pressure will prevail through mid week bringing dry weather and gradually warming temperatures.
High pressure strengthens behind this and remains over the area through Tuesday.
Chase Purdy (Today and tonight) High pressure with a much drier airmass will build into the area today. This will result in mostly sunny skies, light winds, and afternoon high temperatures generally in the low to mid 60s. Overnight lows will generally range from the low to mid 30s with areas of frost, except for the panhandle coast which will stay slightly warmer. The official forecast favors a MOS blend across the Florida big bend outside of urban areas, which usually performs well in radiational cooling regimes by being cooler than the NBM. Tallahassee will likely see its typical warm bubble, with lows in the city in the upper 30s and lows at the airport around freezing.
Otherwise, our next organized batch of widespread rain and snow is forecast to overspread the region from west to east between 11am-3pm today for most areas, lingering across the srn/ern highlands after sunset into tonight, as a low pressure system sits just to our west.
242 AM MST Mon Feb 19 2024 Warmer conditions are expected the next couple days with high temperatures 10 to 15 degrees above normal through Tuesday.
644 AM EST Mon Feb 19 2024 High pressure will prevail through mid week bringing dry weather and gradually warming temperatures.
Upper level ridging is building in today while southwesterly flow develops in response to lee troughing, pushing highs this afternoon back to the 70s for most. This trend will continue into Tuesday as the ridge moves eastward and thicknesses increase with clearing skies, and compressional warming from downslope flow helps usher in well-above normal temperatures. Currently 850mb temps of 20-22C indicate highs peaking into the 80s nearly region- wide, and those along the Rio Grande may be in the low to mid 90s.
-Dry and warmer weather through at least Wed night.
116 PM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
Because of this, nighttime temperatures will cool into the upper 30s with a few areas east of I- 55 reaching near freezing.
356 PM EST Mon Feb 19 2024 High pressure builds in through the middle of the week, maintaining sunny skies and dry conditions.
1120 AM CST Mon Feb 19 2024 A 1024 mb ridge of high pressure centered over the Southeast United States is bringing dry weather and sunny skies to the Mid- South this morning.
(Tonight through Tuesday night) An upper level ridge is moving into TX from the west with northwesterly flow over South Central Texas. A warmer, moister airmass is moving in. Temperatures are 10-15 degrees warmer than 24 hours ago and dewpoints are 15-20 degrees higher. The upper ridge axis will move from west TX to the east side of our CWA during this period. High pressure will continue to dominate in the low levels. Warm advection will mean low temperatures Tuesday morning will be around 10 degrees warmer than this morning. High temperatures will be around 10 degrees warmer than today in the 70s and lower 80s.
Upper ridging slides closer to South Texas on Tuesday leading to warmer temps tomorrow with highs settling into the mid 70s to mid 80s.
1044 AM CST Mon Feb 19 2024 A 1024 mb ridge of high pressure centered over the Southeast United States is bringing dry weather and sunny skies to the Mid- South this morning.
Precipitation chances will begin to increase for the latter half of the week as a cold front approaches. High pressure is building into the area, yielding relatively pleasant winter afternoon weather. High pressure will intensify with abundant dry air in place. High pressure will quickly slide east, and temperatures will begin to moderate being about 5 degrees warmer than today. Eastern Vermont should still be just close enough to high pressure that winds go light and variable with another cold night with single digits, while over the Champlain Valley and northern New York teens to near 20 will be more likely from southerly flow.
1123 AM CST Mon Feb 19 2024 (Today through Tuesday) Fine conditions are expected through the period, with the BRO CWFA on the northern periphery of a 500 mb ridge of high pressure building north out of neighboring Mexico.
There is some low stratus over far southeast Saskatchewan that is trying to drop south of the International Border behind a weak cold front, but it shouldn't impact sky cover much at all this afternoon except maybe a small area along the border. Presently, a west CONUS ridge is located between Pacific low pressure and broad troughing over eastern Canada.
102 PM EST Mon Feb 19 2024 High pressure provides dry, mainly clear weather, with a warming trend, through mid-week. Widespread sub-freezing temperatures are anticipated again tonight as temperatures drop into the mid to lower 20s due to radiational cooling and cold air in place.
It will be a beautiful day across the area, with temperatures trending warmer under full sun, as most Valley locations will reach the mid to upper 50s. The subsidence and dry air, along with slightly warmer temperatures, will result in some low RH values this afternoon; however, with light winds, the fire danger will remain relatively low. Continued clear sky conditions tonight, combined with light winds, will bring another cold night with most locations below freezing once again.
The Lower Valley may, however, escape much of the fog. Speaking of low temps, those should be in the lower to middle 50s tonight. The warmer temps will be a few degrees above normal.
High pressure ridging will be replaced by southwest flow tonight. Precipitation amounts will be light but as road temperatures drop to freezing in the evening, black ice is a concern.
1247 PM EST Mon Feb 19 2024 High pressure centered near our region tonight will slide across New England Tuesday and Tuesday night.
152 PM MST Mon Feb 19 2024 Ridge building over the Intermountain West will allow a warming trend to commence tomorrow.
That disturbance will continue east-southeast tonight with a low-amplitude ridge spreading east into the Great Plains Tuesday into Tuesday night. In the low levels, a weak surface front will move east through the area this afternoon into evening with another subtle boundary moving into northeast NE Tuesday afternoon. A warmer low-level air mass will spread into the region Tuesday with highs warming into mid 50s to mid 60s.
Skies are generally partly cloudy in the Lower Keys, mostly cloudy in the Middle Keys, and overcast in the Upper Keys communities. Low pressure associated with yesterday's frontal passage will slowly intensify as it moves northeastward into the west-central North Atlantic over the next seven days.
Northwest flow aloft this afternoon will gradually transition into upper level ridging by Tuesday evening. This will bring continued mostly clear skies, along with lee troughing being maintained to our northwest. Continued southerly low level flow, combined with a strengthening low level thermal ridge warming by 3 or 4 degrees Celsius at 850mb, high temperatures will also warm several degrees Tuesday, with highs in the upper 70s to mid 80s across the area. (Tuesday night through next Monday) A strengthening upper level high pressure will persist across the region over the next few days.
1114 AM CST Mon Feb 19 2024 (Today through Tuesday Night) An upper ridge located over the Rockies will move into the Plains tonight. The upper ridge remains over the Plains through Tuesday.
Surface marine and land-based observations suggest the cold front that pushed through the Florida Keys overnight is now residing in the vicinity of the eastern Bahamas, extending southwestward to central Cuba. Winds remain a bit elevated, especially in the vicinity of the Lower and Middle Keys. From synopsis, fresh to strong northwest to north breezes in the wake of a cold frontal passage will slacken to moderate to fresh by late this afternoon or early evening.
1052 AM EST Mon Feb 19 2024 Partly to mostly cloudy skies today and Tuesday, with slightly below normal temps, as a pair of upper lows move over the region, but no precipitation is expected.
At the mid-levels, a cutoff low and the associated trough axis will soon exit the southeastern United States into the Atlantic as well. Temperatures tonight will fall into the lower to mid 40s inland over Southwest Florida and portions of the Everglades. The Naples area and the east coast metro should stay in the lower 50s.
Temperatures overnight should be a few degrees warmer than this morning's lows, as low level temperatures increase behind the departing vort max and some wind continuing overnight.
118 PM CST Mon Feb 19 2024 - Quiet and warmer than normal weather to continue.
1058 AM EST Mon Feb 19 2024 High pressure provides dry, mainly clear weather, with a warming trend, through mid-week. High pressure brings dry, mainly clear weather today and tonight. The weak tail end of a cold front may catch far northern portions of the area this morning, but expect nothing more than a few lonely low cumulus clouds beneath the inversion behind it. Return light east to southeast low level flow then ensues tonight, as high pressure bridges across the front to the east of the area. Temperatures will continue a slow uptick, which leaves this morning and tonight still cold, especially in valleys away from rivers with a ridge/valley split, but highs this afternoon will be closer to normal for this time of year.
1044 AM CST Mon Feb 19 2024 (Today and tonight) Warming trend continues today as lee trough brings southwest to west winds 5 to 15 mph. Highs will be in the lower to mid 70s, with the warmest temperatures in the Concho Valley. Overnight lows will be more mild, mainly in the lower 40s.
Slightly cooler overnight lows are expected tonight, with readings falling to near freezing across much of the area. Tuesday night lows are forecast to be a few degrees warmer than tonight's.
At the surface, a high pressure ridge over the area today will shift east of the Appalachians. The main impact of this trough will be to increase high and midlevel clouds during the day, mainly across the southern half.
1003 AM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
1126 AM CST Mon Feb 19 2024 (Today through Tuesday) Light south winds have returned, but are mostly decoupled, leading to some pockets of cold temps that could fall to the freezing mark briefly this morning. A mainly continental surface wind should advect dew points from Deep South TX and not the coast, so the low dewpoints tonight and partial decoupling of surface winds will maintain a good diurnal range and a low temp near seasonal norms for this time of year. Upper ridging building east across TX and a SSW wind low level wind resuming early Tuesday will continue to push the warming trend for Tuesday highs with above normal maxes in the mid 70s to low 80s expected.
I have lowered them slightly to put RH into the low 20s in several areas. Today will begin a warming trend for this week as an upper-level ridge pushes over the southeast later today.
Mid level ridging will amplify over the Southern Plains Tuesday with temperatures climbing well above normal into the upper 70s and lower 80s.
Northerly flow will primarily remain in place through midweek as high pressure continues to build across the FL peninsula, which will keep temperatures below climatological normal values over the coming days despite near full sunshine expected.
This stronger southwest winds aloft also usher in warmer air and will favor temperatures climbing mostly into the lower 50s. The active pattern will push a number of dry cold fronts down across the area, which will mainly impact the temperature and winds forecast for southern Wisconsin.
1121 AM CST Mon Feb 19 2024 (Today through Tuesday) Key Messages: - Quiet pleasant weather today, warmer Tuesday. A strong mid/upper level high pressure system centered over the Pacific to the southwest of Mexico will maintain a subsident northwest flow across S TX today leading to another mostly sunny day. Temperatures will be around 10 degrees warmer today with highs ranging from the mid 60s east to mid 70s west. The upper level high is progged to shift northeast across Mexico and closer to S TX by Tuesday which will lead to highs in the mid 80s across the Brush country. Lows tonight will also be warmer at 45-55 degrees.
Ridging aloft will then assert itself over the CWA for the remainder of the short term, with dry conditions and mild temperatures anticipated. The ridge looks to strengthen over the weekend as a strong pacific trof moves into the western CONUS sending increased short wave activity starting Monday.
910 AM CST Mon Feb 19 2024 - Above normal temps through the middle of the week with highs ranging from the low 40s to 50s. Issued 910 AM CST Mon Feb 19 2024 Freezing fog is improving across far southern Wisconsin this morning. Anderson Issued 418 AM CST Mon Feb 19 2024 Today through Tuesday: Synopsis/Mesoanalysis: Located on the back side of surface pressure ridging, light & variable surface winds prevail across the region early this morning. Surface ridging will continue to migrate east toward the Atlantic coast on Tuesday, with breezy southwest winds becoming established by the afternoon hours.
259 PM EST Mon Feb 19 2024 High pressure builds in from the NW tonight and will crest over the area Tuesday.
1041 AM CST Mon Feb 19 2024 (Rest of Today) High pressure centered over the Southeast has resulted in a chilly start to the day under clear skies and light winds.
Temps not far from expected highs in the lower to mid 60s, relatively cool at the coast due to northeast flow. Based on low dewpoints this afternoon and recent warm bias of the NBM, the freeze watch was upgraded to a freeze warning with up to 2 hours of min temps at freezing, with areas just east of the freeze likely to see some areas to widespread frost.
1230 PM EST Mon Feb 19 2024 High pressure will prevail through mid week bringing dry weather and gradually warming temperatures.
A low pressure system off the northern CA coast will send a wave of moisture through the area late this morning into the afternoon with light precipitation.
1105 AM CST Mon Feb 19 2024 - Near to above normal temperatures will dominate the week ahead, though still some uncertainty how quickly temperatures will warm over the deeper snow cover across the Highway 14 corridor early in the week.
Highs will range from the upper 50s north and northeast to the low 60s south and southwest. Lows will range from the upper 20s far northeast to around freezing south and west.
Northwest flow aloft this afternoon will gradually transition into upper level ridging by Tuesday evening. This will bring continued mostly clear skies, along with lee troughing being maintained to our northwest. Continued southerly low level flow, combined with a strengthening low level thermal ridge warming by 3 or 4 degrees Celsius at 850mb, high temperatures will also warm several degrees Tuesday, with highs in the upper 70s to mid 80s across the area.
1120 AM EST Mon Feb 19 2024 High pressure provides dry, mainly clear weather, with a warming trend, through mid-week. High pressure brings dry, mainly clear weather today and tonight. The weak tail end of a cold front may catch far northern portions of the area this morning, but expect nothing more than a few lonely low cumulus clouds beneath the inversion behind it. Return light east to southeast low level flow then ensues tonight, as high pressure bridges across the front to the east of the area. Temperatures will continue a slow uptick, which leaves this morning and tonight still cold, especially in valleys away from rivers with a ridge/valley split, but highs this afternoon will be closer to normal for this time of year.
107 PM EST Mon Feb 19 2024 High pressure provides dry, mainly clear weather, with a warming trend, through mid-week. Widespread sub-freezing temperatures are anticipated again tonight as temperatures drop into the mid to lower 20s due to radiational cooling and cold air in place.
220 PM EST Mon Feb 19 2024 Strong high pressure builds down the East Coast today. However, dry air in the lower levels, with continued CAA, will keep a dry forecast in place, with the lift and moisture aloft producing little more than virga mainly along the coast. Locally, strong high pressure over New England will bring strengthening cold air damming inland, strengthening the N to NE gradient and keeping below normal temps in place. Dry air will keep rain-free conditions in place across much of the area, though closer proximity to the offshore trough and greater boundary layer moisture content could bring about some showers approaching the coastal waters with one or two possibly pushing far enough west to threaten the OBX.
A ridge of high pressure will bring dry and warmer temperatures to the Mid-South through mid-week.
