1112 AM CST Sun Feb 18 2024 (Today through Monday) A surface cold front and a 500 mb trough have pushed east of the BRO CWFA, leaving dry weather and some cloudiness behind. Finally, with improving, but still elevated, winds and seas courtesy of the passage of the cold front, a High Risk of rip currents will exist at the local beaches until around sunset today.
Tonight: Weak high pressure builds into the forecast area bringing clear skies and light to calm wind. With a very dry airmass in place this should allow for a chilly night, with lows in the lower 20s at most locations. With such a dry airmass still in place a few spots could be warmer than forecast. Monday night: There is a potential (<14% pops) for sprinkles in our southern counties as an upper level trough and h5 low drops southeast out of the Dakotas.
Wind direction to become southerly on Monday as the center of the high shifts southeast. Highs on Monday are forecast to climb into the lower 60s.
113 PM MST Sun Feb 18 2024 Dry, tranquil conditions along with well-above normal temperatures will prevail through the first half of the week as high pressure persists over the region.
215 PM EST Sun Feb 18 2024 Weak high pressure will linger around the region through the middle of the week along with a warming trend.
With the plentiful sunshine across the area, temperatures are warming faster into the low to mid 30s for the Red River Valley and into the Devils Lake Basin. Clusters continue to indicate northwesterly flow continuing through the early portions of this work week, with a breakdown of the ridge out west. As the ridge breaks down and propagates eastward temperatures will start to warm across the area.
(Tonight through Monday night) A cool but nice day is unfolding as high pressure remains in control of the region. Clear skies have allowed for temps to warm a bit with temps currently sitting in the low to mid 50s. Onshore flow will bring warmer temps back with highs rebounding into the mid 60s to mid 70s.
112 PM EST Sun Feb 18 2024 Weak surface ridging persists today, with strong high pressure building down the East Coast beginning Monday. Weak surface ridging and persistent cirrus continue over ENC this afternoon with mainly quiet weather and well below normal temps. This low will remain well offshore, reaching our latitude Tues night.
(Tonight) An upper level trough dropping southeast through the lower MS valley this afternoon, will be over GA by late tonight. Thus, good radiational cooling is expected, so temperatures will dip into the lower to middle 20s for morning lows.
(This evening through Monday) Low temperatures tonight into Monday morning will be chilly, but not as cold as the previous few mornings, with lows hovering near the freezing mark.
919 PM EST Sun Feb 18 2024 A weak cold front passes across the region late tonight.
438 PM CST Sun Feb 18 2024 (This afternoon through Monday night) WV imagery shows dirty ridging over the western CONUS, leaving West Texas under dry, northwest flow aloft.
pdf The widespread light rain over eastern counties will end around midnight, as the low wraps up off the east coast of FL. Cooler and drier air will advect into region from the northwest overnight, which could lead to a little patchy frost for far inland SE GA around dawn.
208 PM MST Sun Feb 18 2024 Satellite imagery indicated a 500mb ridge axis was sliding east of our region at midday while mid level flow backed to the southwest. Late tonight and Monday will be dry and milder under next period of upper level ridging.
454 PM CST Sun Feb 18 2024 (Tonight) An upper level trough dropping southeast through the lower MS valley this afternoon, will be over GA by late tonight. Thus, good radiational cooling is expected, so temperatures will dip into the lower to middle 20s for morning lows.
- System above will cause a lee trough over the central Hi Plains which will keep breezy WNW sfc flow over most of the area tomorrow afternoon.
High clouds/cirrus is increasing from the southwest to northeast while winds remain light due to the influence of surface riding moving east (low pressure starting to build into the region from the west). With the plentiful sunshine across the area, temperatures are warming faster into the low to mid 30s for the Red River Valley and into the Devils Lake Basin. Clusters continue to indicate northwesterly flow continuing through the early portions of this work week, with a breakdown of the ridge out west. As the ridge breaks down and propagates eastward temperatures will start to warm across the area.
Dry, tranquil conditions along with well-above normal temperatures will prevail through the first half of the week as high pressure persists over the region.
530 PM CST Sun Feb 18 2024 (Tonight through Monday night) A cool but nice day is unfolding as high pressure remains in control of the region. Clear skies have allowed for temps to warm a bit with temps currently sitting in the low to mid 50s. Onshore flow will bring warmer temps back with highs rebounding into the mid 60s to mid 70s.
648 PM EST Sun Feb 18 2024 Low pressure passes well to the north tonight, sending a weakening cold front into the region early Monday.
A series of upper level disturbances rotating around a broad trough of low pressure along the West Coast will produce periods of showers through the first half of the week. Weaker upper level ridging will build into the weekend for drier weather.
547 PM CST Sun Feb 18 2024 (This evening through Monday) Low temperatures tonight into Monday morning will be chilly, but not as cold as the previous few mornings, with lows hovering near the freezing mark.
523 PM CST Sun Feb 18 2024 (Tonight through Monday night) High pressure centered over Texas will broaden and shift slowly east. Mid-level ridging upstream will build toward West Texas. North winds will shift to light south overnight as high pressure reorients. Temperatures will start out cooler than normal tonight (by 10 degrees), but after tonight the trend will be warmer. Lows tonight will be in the upper 30s across the northern Ranchlands and Brush Country to the mid 40s for the Lower RGV. Temps Monday night will be near normal again; upper 40s across the northern Ranchlands and Brush Country to the mid 50s for the Lower RGV.
Overnight, clear skies will allow for efficient cooling as we tumble over 20 degrees to the low-to-mid 20s.
The break in precipitation is short-lived, with the next trough arriving with precipitation Mon afternoon for western zones, spreading into the Snake River plain and the eastern ones by mid- day. This trough also does not have the upper level support for strong lift or strong wind, so it does not at this time warrant any kind of headline. This trough appears to peak during Mon evening, with a tailing off for the late night hours. Temperatures during this period will be warm enough in the valleys to support rain so any snowfall accumulations during this period will be focused primarily across the higher terrain.
912 PM EST Sun Feb 18 2024 Low pressure will pass offshore of the Southeast U.
652 PM EST Sun Feb 18 2024 Weak surface ridging persists tonight, with strong high pressure building down the East Coast beginning Monday. At the surface, weak ridging persists, with very dry low levels and no rain chances. Lows will be near to a few degrees below freezing for most early Monday morning, with the surface airmass likely too dry for event ground fog formation. Temps near normal/upper 50s for most, but cooler for Northern OBX/Albemarle Sound area with CAA coming off the chilly waters. This low will remain well offshore, reaching our latitude Tues night.
730 PM EST Sun Feb 18 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
543 PM CST Sun Feb 18 2024 (This evening through Monday Night) High pressure has taken control of our weather with clear skies, light winds, and dry conditions. Lows will again get down to near freezing for areas north of the Houston Metro with the Piney Woods area possibly getting into the upper 20s. The high pressure over the region today will begin to slide eastwards tomorrow. Afternoon high temperatures will rise into the low to mid 60s. The southerly flow will continue to work its magic Monday night with overnight low temperatures in the low to mid 40s - about a 10 degree change from tonight's expected lows.
306 PM CST Sun Feb 18 2024 Tonight through Tomorrow: Subsidence in the wake of an upper-level trough axis has been working to clear sky cover over the region today.
Made minor adjustments to temperatures and dew points this evening as a few spots in the region have remained warmer than previously anticipated. Opted to retain the inherited ridge/valley split for overnight temperature trends. With decent ridge/valley splits, some valleys may wind up cooler tonight than they were this past night. Mountain lows in the teens and lower elevation lows in the low to mid-20s are expected, with sheltered valleys likely 5-10 degrees cooler than surrounding ridges.
532 PM CST Sun Feb 18 2024 - Steadily warmer temperatures are forecast through the middle of the week.
941 PM EST Sun Feb 18 2024 High pressure and dry conditions will persist overnight. Tonight Through Monday Night: A weak and moisture starved upper level trough will swing through the region tonight and Monday morning. No precipitation is expected with the trough, but it should increase mid level cloud cover tonight and Monday morning. Though pressure gradients in the lee of the Appalachians aren't overly strong with the high, they my be sufficient to push a weak wedge front into northeast Georgia Monday. Weak upper level ridging and the return of sunny skies should help temperatures trend upward Monday afternoon.
(Tonight) An upper level trough is continuing to shift southeastward this evening and overnight. Low temperatures are forecast to drop into the low to mid 20s coupled with light and variable winds.
641 PM EST Sun Feb 18 2024 Weak high pressure will linger around the region through the middle of the week along with a warming trend.
Breezy north winds will continue overnight as the frontal boundary pushes away and high pressure builds in from the west through the first half of the week.
517 PM CST Sun Feb 18 2024 A ridge of high pressure will bring a continuation of dry weather to the Mid-South through mid-week.
A ridge of high pressure will bring a continuation of dry weather to the Mid-South through mid-week.
712 PM CST Sun Feb 18 2024 - Quiet, warmer than normal weather to continue. This melting is ongoing despite temperatures that are generally in the low to mid 30s across the MPX coverage area, with the mid February sun angle (roughly equivalent to mid- October) beginning to work in earnest.
1015 PM CST Sun Feb 18 2024 (This evening through Monday) Low temperatures tonight into Monday morning will be chilly, but not as cold as the previous few mornings, with lows hovering near the freezing mark.
1133 PM CST Sun Feb 18 2024 (This evening through Monday Night) High pressure has taken control of our weather with clear skies, light winds, and dry conditions. Lows will again get down to near freezing for areas north of the Houston Metro with the Piney Woods area possibly getting into the upper 20s. The high pressure over the region today will begin to slide eastwards tomorrow. Afternoon high temperatures will rise into the low to mid 60s. The southerly flow will continue to work its magic Monday night with overnight low temperatures in the low to mid 40s - about a 10 degree change from tonight's expected lows.
1255 AM EST Mon Feb 19 2024 Mainly clear and dry with a warming trend through mid-week, with high pressure in control. 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.
Presently, a west CONUS ridge is located between Pacific low pressure and broad troughing over eastern Canada. The main impact will be a windshift to a more northwesterly direction with slightly cooler highs across the forecast area compared to yesterday (Sunday). The main exception will be the far northwest where temperatures may be as much as 5 to 10 degrees cooler than yesterday. The ridge will flatten out as it gradually works eastward through the middle of the week. That said, with the flattening ridge, there will likely be a large spread in high temperatures for areas along the ND/Canadian border compared to those further south.
/DC/ Tonight through Tomorrow: Subsidence in the wake of an upper-level trough axis has been working to clear sky cover over the region today.
(Today) Tranquil weather across the Tennessee Valley region this morning, with high pressure prompting clear/calm conditions.
1112 PM CST Sun Feb 18 2024 (This afternoon through Monday night) WV imagery shows dirty ridging over the western CONUS, leaving West Texas under dry, northwest flow aloft.
I can't see how any precipitation can make it to the ground, given the dryness of the low levels. Dry conditions in the lower and middle levels are resulting in only some high clouds. Highs will range from the upper 50s north to the low 60s far south.
1228 AM EST Mon Feb 19 2024 Weak high pressure will linger around the region through the middle of the week along with a warming trend.
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.
1040 PM CST Sun Feb 18 2024 (Tonight through Monday night) High pressure centered over Texas will broaden and shift slowly east. Mid-level ridging upstream will build toward West Texas. North winds will shift to light south overnight as high pressure reorients. Temperatures will start out cooler than normal tonight (by 10 degrees), but after tonight the trend will be warmer. Lows tonight will be in the upper 30s across the northern Ranchlands and Brush Country to the mid 40s for the Lower RGV. Temps Monday night will be near normal again; upper 40s across the northern Ranchlands and Brush Country to the mid 50s for the Lower RGV.
1256 AM EST Mon Feb 19 2024 Low pressure will pass offshore of the Southeast U.
1109 PM CST Sun Feb 18 2024 - Steadily warmer temperatures are forecast through the middle of the week.
247 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.
1050 PM CST Sun Feb 18 2024 (Tonight) An upper level trough is continuing to shift southeastward this evening and overnight. Low temperatures are forecast to drop into the low to mid 20s coupled with light and variable winds.
1233 AM EST Mon Feb 19 2024 High pressure will prevail through mid week bringing dry weather and slowly warming temperatures.
(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.
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.
223 AM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
An upper level trough continues to work its way eastward across the Gulf of Mexico. As a result winds have been heavily perturbed by both the presence of the low and the rather recent development of fast moving strong showers. In their wake, winds will become more uniformly fresh out of the northwest to north and drive a cold front southeastward through all of the Keys. Expect overnight to settle broadly in the lower to mid 60s with dew points falling sharply towards 60 and possibly upper 50s.
334 AM EST Mon Feb 19 2024 High pressure will prevail through mid week bringing dry weather and gradually warming temperatures.
1024 PM EST Sun Feb 18 2024 Weak high pressure will linger around the region through the middle of the week along with a warming trend.
231 AM EST Mon Feb 19 2024 Mainly clear and dry with a warming trend through mid-week, with high pressure in control. 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.
1016 PM EST Sun Feb 18 2024 Strong high pressure builds down the East Coast beginning Monday. That being said, still expecting freezing temps west of Highway 17 with mid 30s for the coastal areas and Outer Banks. Temps near normal/upper 50s for most, but cooler for Northern OBX/Albemarle Sound area with CAA coming off the chilly waters. This low will remain well offshore, reaching our latitude Tues night.
Skies have stayed cloudy behind this morning's warm front and should keep nighttime temps mild ahead of the next weaker warm front, due in eastern OR Monday morning and western ID Monday afternoon.
200 AM MST Mon Feb 19 2024 High confidence (90%) remains for a dry and warmer than normal week ahead. The upper level flow pattern turns more northwesterly by midweek as a ridge builds eastward over the region.
Low pressure strengthening off of the east central Florida coast this evening, which can even be seen as a mesoscale circulation on KMLB radar around 9PM. As the low continues to strengthen, winds have increased along the coast, especially in Brevard County. Dangerous marine conditions continue to develop, as low pressure strengthens off of the east central Florida coast. (00Z TAFS) IFR/very low MVFR conditions prevailing this evening, as low pressure strengthens off of the east central Florida coast. Low CIGs will persist through much of Monday morning, lifting from west to east into the afternoon, as the low pulls away from the area and into the Atlantic.
1033 PM CST Sun Feb 18 2024 (Tonight through Monday night) A cool but nice day is unfolding as high pressure remains in control of the region. Clear skies have allowed for temps to warm a bit with temps currently sitting in the low to mid 50s. Onshore flow will bring warmer temps back with highs rebounding into the mid 60s to mid 70s.
1048 PM CST Sun Feb 18 2024 - Quiet, warmer than normal weather to continue. This melting is ongoing despite temperatures that are generally in the low to mid 30s across the MPX coverage area, with the mid February sun angle (roughly equivalent to mid- October) beginning to work in earnest.
High pressure and dry conditions will persist overnight. Tonight Through Monday Night: A weak and moisture starved upper level trough will swing through the region tonight and Monday morning. No precipitation is expected with the trough, but it should increase mid level cloud cover tonight and Monday morning. Though pressure gradients in the lee of the Appalachians aren't overly strong with the high, they my be sufficient to push a weak wedge front into northeast Georgia Monday. Weak upper level ridging and the return of sunny skies should help temperatures trend upward Monday afternoon.
1245 AM EST Mon Feb 19 2024 A weak cold front passes across the region late tonight.
A weak low pressure system will pass by to the south today, and this will keep mid to high level clouds around to the south with mostly sunny skies north. Winds are expected to become east to southeast, and this will create some cooler- by-the-lake conditions in the Arrowhead, especially in the higher terrain with upslope flow. Temperatures will stay on the warm side with highs in the 30s, with cooler highs in the 20s in the Arrowhead. A broad ridging pattern over the western CONUS will keep a steady push of weak, but persistent, warm air advection over the region through mid-week. Mixed clouds and sun are expected with weak disturbances riding the broader ridge aloft.
The trough will approach the I-35 corridor by afternoon before washing out and dissipating.
Complex area of low pressure offshore maintains showers through mid-week. As the storm track shifts south of the area, high pressure builds over the Pac NW, will see dry and mild weather for later this week. Complex area of low pressure off the coast of northern California maintains unstable southerly flow with showers across parts of SW Washington, NW Oregon.
536 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.
626 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.
628 AM EST Mon Feb 19 2024 Weak high pressure lingers through the middle of the week along with a warming trend.
At the surface, a broad area of low pressure currently over the area will gradually track eastward today, then will see high pressure settle in tonight and Tuesday. Highs on Tuesday will be in the upper 30s to the lower 50s. A ridge to the south and trough to the north will enhance flow aloft mid-week, with a transition towards a stronger eastern CONUS upper trough.
Presently, a west CONUS ridge is located between Pacific low pressure and broad troughing over eastern Canada.
526 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.
