1240 PM EST Sun Feb 9 2025 High pressure will shift east across the region today through Monday, leading to dry and seasonable conditions.
/CR/ Today and tonight: A cold front is currently pushing southward across the area. So far, shower activity has been limited along the front, but it is ushering in low clouds and a cooler airmass in northerly CAA. The front will be clear of the entire area by tonight, with cooler conditions areawide. That being said temperatures will trend a few degrees cooler north of I-20 with southern counties/parishes seeing a continuation of relatively balmy temperatures.
222 PM EST Sun Feb 9 2025 A cold front will continue to push south through the area this afternoon. High pressure ridging will then briefly build in behind this front from the north but will quickly push offshore by Monday evening. This unsettled pattern will continue into the end of the week before high pressure ridging builds into the area from the west. Latest analysis shows cold front pushing through the southern portions of the forecast area early this afternoon. High pressure will build in from the NNW tonight as cold front continues to sink southward, while strong isentropic lifts spreads over the area. Much cooler tonight with CAA behind the front, with lows falling into the upper 30s to low 40s.
107 PM EST Sun Feb 9 2025 With the low pressure system east of the region, lake effect snow develops later today off of Lake Ontartio. The cold front is moving through with the freezing drizzle coming to an end. Some patchy freezing drizzle may persist at higher elevations through about 10 am.
Temperatures will be a few degrees less than yesterday, and as much as 10 degrees cooler in the Four Corners region.
Meanwhile, latest surface analysis places a cold front from northern Georgia back through central Texas. CJC Much cooler temperatures will prevail over the Midsouth today, following last evening's cold frontal passage.
1124 AM CST Sun Feb 9 2025 Updated at 1119 AM CST Sun Feb 9 2025 A dense fog advisory for morning along and south of I-10 Two cold fronts to push through: today and mid week.
(This afternoon through Monday Night) The persistent zonal flow aloft continues today, and this currently coincides with northeasterly surface winds across the Tennessee Valley thanks to high pressure to our north.
1004 AM CST Sun Feb 9 2025 Updated at 300 AM CST Sun Feb 9 2025 - Low chance of light freezing rain this morning in higher terrain areas of northwest Arkansas.
Some adjustments were made to the forecast, mainly to remove fog in areas where no fog is present, except for Alturas where they are reporting freezing fog.
Temperatures will remain above normal with highs today and Monday in the low to mid 80s across the east coast metro and mid to upper 80s across SW FL. Low temps tonight will be in the lower 60s around the lake, to mid and upper 60s elsewhere.
- Light snow showers will develop across western WY today with the heaviest snow remaining in the higher elevations. Highs on Sunday will be on the cooler side ranging from the upper teens west of the Divide to upper 20s east of the Divide. The current forecast shows snow showers remaining mostly across the higher elevations of northern/central WY. The setup looks to be a deep trough that digs across the western CONUS. The southerly extent of the trough will be a key factor in determining what and where impacts will be seen. The next weather feature is a cold front moving through Monday.
The clear skies, drier air, and light winds will allow very cold low temps Monday morning in the higher Idaho basins. Meanwhile, northwesterly flow aloft will become temporarily westerly on Monday as a short wave trough approaches from BC.
Cold temperatures continue with Monday daytime highs a few degrees cooler than today.
(This evening through Monday) Broad ridging remains in control across the Florida peninsula as the upper-level pattern continues to be zonal in nature. Most locations to the east are in the low 80s. This is due to the cooler water temperatures along the coast. Water temperatures are warmer - too warm for the air temperature to reach the dewpoint and condense.
1236 PM EST Sun Feb 9 2025 - Outside of some light lake enhanced flurries or patchy freezing drizzle early this morning, expect dry conditions with partly to mostly cloudy skies today.
558 PM CST Sun Feb 9 2025 (This evening through Monday Night) Winter norms have yet to return to deep east TX and the lower half of Toledo Bend country. Both Lufkin and Peason Ridge have seen lower 80s earlier this afternoon. A big change for most of us overnight with high pressure finally settling back for a long haul. The 1034mb high this morning started over NB/MO and has weaken to 1031mb with daylight, but a weak inverted trough has developed over the last several hours over deep east TX holding the backdoor closed. Amounts will remain on the light side through the short term with highs tomorrow in the low 40s to low 60s.

214 PM MST Sun Feb 9 2025 - 1 to 3 inches of new snow possible across the eastern San Juan Mountains overnight tonight, with warmer temperatures expected Monday afternoon.
High pressure stretched across Florida remains the dominant weather feature over the region. Areas of fog will be possible once again overnight for the eastern gulf waters and land areas, with the highest coverage inland and north of Tampa Bay. Sea fog will remain a marine hazard for the next few days as high pressure and lights winds and seas continue.
430 PM MST Sun Feb 9 2025 - Passing cold front will bring very cold air for the first half of the week, with light snow on Monday. Current surface analysis shows high pressure east of the region, with an arctic cold front near the Montana-Canadian border. An upper low is situated over the northern Prairie Provinces. Cold front to the northwest is progged to pass across the area late tonight and Monday, bringing another surge of arctic air for the first half of the week.
600 PM CST Sun Feb 9 2025 Updated at 555 PM CST Sun Feb 9 2025 Two cold fronts to push through: today and mid week.
709 PM EST Sun Feb 9 2025 * High pressure will build east into the region Monday and become centered over the state Monday night, bringing seasonably cool and fair conditions.
The cold front had reached the Pine Belt of southern MS, but warmer pre-existing conditions were slowing daytime progression there and temps were in the 80s at Hattiesburg, McComb and Columbia.
By tomorrow our attention will turn to what looks to be the first of potentially three snowfall events during the valid period as waves eject out of the current CA trough. Mid level moisture is spotty, however this cooler airmass drops the dendritic growth zone (DGZ) lower where more moisture is available.
513 PM CST Sun Feb 9 2025 A series of upper-level systems will move across the Lower Mississippi Valley this week.

Temperatures will remain above normal with highs today and Tuesday in the low to mid 80s across the east coast metro and mid to upper 80s across southwest Florida. Tonightâs low temperatures will be in the low 60s around Lake Okeechobee with mid to upper 60s elsewhere.
130 AM MST Mon Feb 10 2025 - Light snow today into Tuesday, especially across the Black Hills and southern SD - Very cold temperatures through midweek, and then a brief warmup Thurs/Fri - Chances for snow return Fri/Sat Broad upper trough covers much of the CONUS. At the surface, cold high pressure is sinking into the northern plains behind the cold front. As cold air continues to filter into the region, highs today won't be much warmer than the morning lows, only in the single digits to teens.
1025 PM MST Sun Feb 9 2025 - 1 to 3 inches of new snow possible across the eastern San Juan Mountains overnight tonight, with warmer temperatures expected Monday afternoon.
High pressure over the western North Atlantic will maintain gentle to moderate easterly breezes across the Keys coastal waters through Tuesday. Moderate breezes will veer to the southeast by midweek, as high pressure retreats further offshore into the Atlantic.
1104 PM CST Sun Feb 9 2025 A series of upper-level systems will move across the Lower Mississippi Valley this week.
1204 AM CST Mon Feb 10 2025 The cold front has pushed south of the Highway 84 corridor and most of the forecast area is in a cold advection pattern now. The cold front had reached the Pine Belt of southern MS, but warmer pre-existing conditions were slowing daytime progression there and temps were in the 80s at Hattiesburg, McComb and Columbia.

(Monday through Tuesday) Near zonal flow aloft continues across our region early this morning, however, return to southwest flow aloft is not far away thanks to a long wave trough moving through the western CONUS. At the surface, the cold front responsible for our cooler temperatures has moved into the Gulf and another cold front is currently moving through the High Plains. By this evening, the Gulf cold front will begin to lift back to the north as a warm front while the cold front moving through the High Plains will continue to push south. Temperatures today and Tuesday will be well below normal with highs ranging from the lower 40s across our northern zones to the lower 60s across our southern zones.
1012 PM EST Sun Feb 9 2025 A cold front will continue to push south through the area this afternoon. High pressure ridging will then briefly build in behind this front from the north but will quickly push offshore by Monday evening. This unsettled pattern will continue into the end of the week before high pressure ridging builds into the area from the west. Cold front has moved little since the last update, now just south of Onslow County per regional observations. Much cooler tonight with CAA behind the front, with lows falling into the upper 30s to low 40s.
Right now the highest confidence is in the southeast later tonight through Monday morning.
A strong U/L subtropical ridge persists over the Gulf and Florida. The U/L pattern will finally begin to breakdown with a L/W trough gradually developing over the inter-mountain west by mid week. This will suppress the U/L ridge over Florida to the south and east, with the southern extent of the westerlies dipping down over northern Florida. An area of low pressure will develop over the Lower Mississippi Valley along a strong baroclinic zone as arctic air dives south through the plains associated with this pattern change.
243 AM CST Mon Feb 10 2025 - First disturbance comes through tonight through Tuesday evening bringing rain, sleet, freezing rain, and snow.
1145 PM CST Sun Feb 9 2025 Updated at 1141 PM CST Sun Feb 9 2025 Two cold fronts to push through: today and mid week. (Tonight through Monday night) Another unseasonably warm day ongoing with a weak cold front just knocking at the door of our northern border of the CWA.
514 AM CST Mon Feb 10 2025 - Mainly dry this afternoon-evening with chances for any light snow accumulations (trace amounts) are generally across far northern Kansas, near the highway 36 corridor.
Above normal temperatures look to stick around a couple of more days, before cooler conditions return for the rest of the week.
318 AM CST Mon Feb 10 2025 - Mainly dry this afternoon-evening with chances for any light snow accumulations (trace amounts) are generally across far northern Kansas, near the highway 36 corridor.
528 AM CST Mon Feb 10 2025 (Today through Tuesday) The most recent surface analysis pegged a weak cold front knocking on the door of the BRO CWFA. This front is expected to stall before returning to the north as a warm front during the period. Overall, the proximity of this boundary may generate a few isolated showers across Deep South Texas and the Rio Grande Valley today, with dry weather returning for tonight and Tuesday as the boundary transitions to a warm front and moves away. Finally, building seas along the Lower Texas Coast, beginning on Tuesday, will result in a moderate risk of rip currents at the local beaches at that time.
Will continue to see an upper low over western Hudson Bay and several shots of fresh arctic air dropping south into the the area as we heed thru the next 7 days.
501 AM EST Mon Feb 10 2025 * High pressure will build east into the region today before becoming centered over the Commonwealth tonight.
956 AM EST Mon Feb 10 2025 * High pressure will build east into the region today before becoming centered over the Commonwealth tonight.
724 AM EST Mon Feb 10 2025 * High pressure will build east into the region today before becoming centered over the Commonwealth tonight.

537 AM CST Mon Feb 10 2025 - First disturbance comes through tonight through Tuesday evening bringing rain, sleet, freezing rain, and snow.
Cooler and drier weather is expected through Tuesday. There is a 30 to near 100 percent chance of freezing temperatures across the San Joaquin Valley Tuesday morning. More freezing temperatures and in the southern portion of the Valley stratus greeted us this morning. The freezing mornings stick with us on Tuesday as ensembles agree that a trough slides into the Great Basin leading to a continuation of cold air moving in from Canada. A Freeze Warning remains in effect through Tuesday morning with a 30 to 100 percent chance of freezing temperatures across the Valley.
Winds will remain out of the north today into tonight before a warm front lifts northward across the area during the day Tuesday shifting winds to be out of the southeast. Overall temperatures tonight will fall into the lower to middle 50's along and northwest of the I-65 corridor with upper 50's to lower 60's southeast. Tuesdays highs will be notably warmer than today with temperatures making it into the middle to upper 70's for most locations thanks to the northward moving warm front. Tuesday night will be unseasonably warm once again with lows in the lower to middle 60's for most locations, warmest nearer the coast.
- Total rainfall amounts for the week will range from 3 to 7 inches, with the highest amounts occurring across north Mississippi.
05" of precipitable water is mostly confined to the lower levels. The prevailing synoptic feature is high pressure centered just to our east, and in theory this should spell out quiet weather. Looking in the lowest levels near the surface, there does appear to be the tiniest amount of veering in the wind direction, implying that there is some sort of lift in this area. High pressure over the western North Atlantic will maintain gentle to moderate easterly breezes across the Keys coastal waters through Tuesday. Moderate breezes will veer to the southeast by midweek, as high pressure retreats further offshore into the Atlantic.
(Tonight) By this evening, an 8h warm front will have lifted into central AR east to along the TN state line. Temperatures will remain nearly steady overnight due to warm/moist southerly flow, with mins in the lower to middle 40s.
Highs will have substantial differences north to south as areas north of the boundary near I-20 will likely stay in the lower to mid 50s F (some areas in the northwest will struggle to get out of the 40s F) with temperatures in the mid and upper 60s F to the south. /86/ Today and tonight: We will remain in a cloudy and cooler post frontal regime through the near term.
1141 AM CST Mon Feb 10 2025 - Mainly dry this afternoon-evening with chances for any light snow accumulations (trace amounts) are generally across far northern Kansas, near the highway 36 corridor.
The rest of the week still looks like it will overall be a pleasant one as high pressure remains the dominant pattern over our region.
pdf A weak cold front has slowly made its way southward into SE GA and will push south into northeast Florida overnight before stalling.
1053 AM MST Mon Feb 10 2025 - Light snow today into Tuesday, especially across the Black Hills and southern SD - Very cold temperatures through midweek, and then a brief warmup Thurs/Fri - Chances for snow return Fri/Sat Broad upper trough covers much of the CONUS. At the surface, cold high pressure is sinking into the northern plains behind the cold front. As cold air continues to filter into the region, highs today won't be much warmer than the morning lows, only in the single digits to teens.
Strong ridging will continue to be the dominating weather influence for much of the week.
1210 PM PST Mon Feb 10 2025 A cold front will pass through Northeastern Nevada Tuesday afternoon into Tuesday evening, resulting in a slight chance of snow showers.
1238 PM CST Mon Feb 10 2025 - First disturbance comes through tonight through Tuesday evening bringing rain, sleet, freezing rain, and snow.
702 PM EST Mon Feb 10 2025 Strong ridging will continue to be the dominating weather influence for much of the week.
Lapse rates near the surface are steep due to the very cold air just off the warmer ground, especially downstream of areas with low snow pack. Coldest temps will be west of the Red River Valley, and will align with the higher wind values.
Otherwise, hi-res guidance continues to suggest some patchy fog may develop across land areas overnight as well as offshore for mainly northern marine zones where cooler SST values in the mid/upper 50s remain. Strong ridging will continue to be the dominating weather influence for much of the week.
An slowing cold front will approach the area Tuesday producing widespread precipitation across the region from late morning through late evening.
A series of progressively stronger low pressure troughs will impact northern Arizona this week.
The dense cloud cover will also prevent temperatures from dropping much tonight, with most locations remaining in the low to mid 40s. Eventually the surface front will also shift southeast with the precip area, while 8h flow continues to overrun the low level cool air. The warm front lifts northward again Wednesday with light to moderate rain showers.
Exception is a strong U/L ridge which extends across the Gulf and Florida. A L/W trough will take shape over the western U. This will gradually suppress the U/L ridge, with the southern extent of the westerlies dipping down over the northern Florida peninsula. An area of low pressure will develop tomorrow over the Lower Mississippi Valley along the baroclinic zone/frontal boundary, and will track rapidly northeast across the Ohio River Valley and eastern Great Lakes late tomorrow and tomorrow night.
From synopsis, high pressure over the western North Atlantic will maintain gentle to moderate easterly breezes across the Keys coastal waters through Tuesday. Moderate breezes will veer to the southeast by midweek, as high pressure retreats further offshore into the Atlantic. A deepening trough over the southeastern U.
MVFR cigs will persist at MLU overnight, and eventually develop by 09Z at LFK as the scattered -SHRA increase, before the lower IFR cigs set in by daybreak.
Deep moisture will stream northward from the Gulf and mid and upper level winds become southwesterly and move over the lower- level boundary.
- A mixture of freezing rain and snow is likely over portions of east central Illinois on Wednesday, causing some light ice accumulations. Continued isentropic ascent across southern Illinois overnight will eventually help to saturate the lower levels mainly south of I-70 after midnight allowing light snow to eventually materialize with a dusting possible through daybreak Tuesday. Afternoon water vapor imagery shows a well defined wave dropping south along the British Columbia coast, and this will help dig the upper trough over the southwest U. This also introduces a larger area over east central Illinois where freezing rain or sleet will be a concern. Forecast soundings off the NAM (though somewhat degraded due to data ingest issues this morning) and GFS do not show an overwhelmingly strong signal for freezing rain, but may be more supportive of sleet.
Mid/upper-level high pressure dominates most of the southwest Caribbean. The aforementioned front will gradually push northward, allowing for the ridge to further expand across the area. In terms of temperatures, the prevailing high pressure will keep afternoon highs in the low-mid 80s across the east coast metro, and mid-upper 80s across southwest Florida. Morning lows should remain in the low 60s over interior areas, and mid to upper 60s near the coasts.
- Total rainfall amounts for this week will range from 3 to 7 inches, with the highest amounts occurring across north Mississippi.
