719 AM EST Mon Jan 27 2025 (Today through Tuesday) A mid-level trough axis will push a frontal boundary into the southeastern United States today and pinch high pressure back over the peninsula of Florida.
412 AM MST Mon Jan 27 2025 - Dry, calm, and warmer through the workweek.
Cooler air in the wake of the cold front tonight will make for a mix of foggy and frosty conditions overnight. Considering the rain yesterday into today, saturated ground will keep low-level humidity in place as skies begin to clear and cooler temperatures settle in. Overnight temperatures will drop several degrees cooler than this afternoon's "crossover temperatures", resulting in a good chance for dense fog development.
(Now through Tuesday Night) A weak cold front will continue to move southward across the area today as a large trough digs across the northeast states. Lows tonight will be much cooler, in the mid and upper 30s inland to low 40s along the coast. Tuesday will be dry with highs in the low 60s.
Winds veer west around sunset, then northwest into this evening as a cold front passes through.
Closer to the surface, sw to w winds will continue to advect in warmer air. This mixing will lead to strong gusty winds, warmer temperatures and even drier low level air. Overall NW to W flow will advect in warmer and drier air from the NW as adiabatic compression helps to warm the column.
304 AM MST Mon Jan 27 2025 -Dry and mild weather this week -Breezy at times, especially today across northwest SD -Turning cooler and unsettled later this weekend Western NOAM Rex block will support mild and dry weather this week as Pac air spreads back into the region under the bending upper ridge. Low pressure trough will advect through the region today and act as a warm front as Pac air spreads back into the region. Much warmer today most places, although temps will be tricky where snow pack remains, today and the rest of the week. Mild weather will persist through the end of the week at which time a deep upper trough will shift south into the northern CONUS.
533 AM CST Mon Jan 27 2025 (Today) A frontal wave of low pressure continues to shift ENE into the central Gulf Coast, bringing rain showers into the Tennessee Valley.
229 AM PST Mon Jan 27 2025 * Brisk northeast to east ridge winds will continue through Tuesday night.
Very mild south of the front today with highs today in the low to mid 30s in all areas, though peaking early aftn in far NW MN and far NE ND before falling by 00z. With the sfc front and 850 cold front that will hang out in NE ND into NW MN later today and evening some very light snow is possible and maintained a 20 pop in this area late today/evening. Warm advection and frontogenetical forcing southeast of the low will generate a band of snow that will skirt the far northeast fcst area (Roseau-Waskish-Waroad-Baudette) late tonight into Tues AM. Up and down temp pattern continues with colder air returning to NW MN Tues night-Wed (with 20s for highs Wed) while abovfe freezing highs SE ND.
404 AM MST Mon Jan 27 2025 - Dry and slightly warmer today.
(Today) A frontal wave of low pressure continues to shift ENE into the central Gulf Coast, bringing rain showers into the Tennessee Valley.
00"+ for many coastal and valley areas, with 1-10"+ inches of snow for the higher elevations. On and off showers with additional light precipitation will continue through early afternoon, tapering off this evening as the upper level low pivots eastward towards the CA/AZ border.
137 PM MST Mon Jan 27 2025 - Dry and mild this week with gusty winds at times - Turning colder and unsettled later this weekend 20z surface analysis had weak trough from southern MN into northwest SD, which has turned into a weak localized cold front due snow-cooled air across southeast MT/northwest SD/southwest ND. Main concern this forecast will be disposition of cold front for the weekend.
318 PM EST Mon Jan 27 2025 A weak area of low pressure will bring clouds and increasing rain chances today.
A stretch of warmer weather has begun in the region.
1112 AM CST Mon Jan 27 2025 (Rest of Today) Rain has come to an end across the area and drier air will filter in today in the wake of a cold front. High pressure will begin to build into the area as an upper ridge sits just to our west, keeping temperatures a bit warmer than we've seen in recent days.
The next several days will feature a series of ridges moving across the region, differing in size, strength, and placement. The first one which we've already mentioned will continue to contract and shift east in response to the next ridge moving in from across the central Gulf of Mexico. In response winds will back towards the north and we could a little bit of drier air and slightly cooler temperatures for Tuesday.
Widespread rainfall and cloud cover will hamper daytime heating keeping high temperatures in the low 50s to upper 40s. Rainfall should end and shift east of the area by 00z with no rain expected overnight and some clearing of the lower clouds after midnight as drier air pushes into the region on westerly winds behind the cold front. With dry air and clearing skies above lingering low level moisture there may be brief periods of patchy fog but the low level mixing should prevent widespread fog. Cold advection should help min temperatures fall into the lower to mid 30s.
As anticipate low level moisture associated with a low level ridge in the western Caribbean has nudged slightly northwestward overnight and into this morning. Otherwise, at the surface we remain under the influence of a weakening high pressure that has moved into the southeast U. This will bring the ridge axis closer to our area and lead to a slackening of winds and act to gradually shove the moisture back south.
1235 PM EST Mon Jan 27 2025 A weak area of low pressure will bring clouds and increasing rain chances today.
1011 AM MST Mon Jan 27 2025 - Dry, calm, and warmer through the workweek.
Patchy fog and freezing fog overnight. Light wintry mix expected across the highest elevations with light accumulations of 1/2 inch or less of snow.
However, the low clouds over I-30 will be tougher to go with these light wind speeds and near saturation readings. /24/ (Tuesday Night through Monday) By tomorrow evening, the aforementioned upper level trough will continue to deepen and amplify around a robust closed low over the Four Corners region. As this low pushes eastward, the weak ridging over the ArkLaTex will likewise be nudged out, making way for southwesterly flow aloft.
Will be another clear day as high pressure builds in aloft.
High pressure building will keep us dry with stronger inversions through the end of the week. We MAY see a few pockets of stratus and/or freezing fog.
312 PM EST Mon Jan 27 2025 A surface trof will pass through the area Tuesday.
- Cold Front Will Cross the Area Tuesday with a Brief Cool Down Tue Night.
1026 AM MST Mon Jan 27 2025 -Dry and mild weather this week -Breezy at times, especially today across northwest SD -Turning cooler and unsettled later this weekend Western NOAM Rex block will support mild and dry weather this week as Pac air spreads back into the region under the bending upper ridge. Low pressure trough will advect through the region today and act as a warm front as Pac air spreads back into the region. Much warmer today most places, although temps will be tricky where snow pack remains, today and the rest of the week. Mild weather will persist through the end of the week at which time a deep upper trough will shift south into the northern CONUS.
Additionally, strong warm air advection along this boundary will allow for temperatures to get above freezing tomorrow.
(Rest of Today) Rain has come to an end across the area and drier air will filter in today in the wake of a cold front. High pressure will begin to build into the area as an upper ridge sits just to our west, keeping temperatures a bit warmer than we've seen in recent days.
1214 PM MST Mon Jan 27 2025 - Dry and tranquil weather with warmer temperatures expected much of the work week.
(Rest of Today) Clouds have been slow to clear north/central AL in the wake of a cold front, but high pressure moving into the region will aid in nudging this cloud deck to our south. Temperatures have remained in the low to mid 40s in most locations, with a few spots in NE AL approaching 50 degrees. Clear skies and light winds will allow for one more night below freezing as radiational cooling brings lows down to the mid to upper 20s.
1030 AM MST Mon Jan 27 2025 - Dry and slightly warmer today.
(This afternoon through Tuesday) As a mid-level trough axis continues to push a frontal boundary into the southeastern United States, it will pinch high pressure back over the peninsula of Florida today.
Issued by National Weather Service Peachtree City GA 1134 AM CST Mon Jan 27 2025 (Today through Tuesday) This AM areas of rain are present across C AL ahead of a cold front. Cooler temperatures are expected for tonight behind the front as clouds clear across the NW 1/2 and decrease across the SE. Lows will run from the mid/upper 20s N to the low/mid 30s S. Ample sunshine is expected for Tuesday as surface ridging settles over the Deep South with highs expected in the 50s and possibly a few lower 60s in the far S.
The weather pattern remains a quiet one through the rest of the week with high pressure the dominant feature. The only slight change in the line up this week will be a weak cold front moving through the area tomorrow. However, with high pressure building back in behind the front, a steady increase in temperatures continues as the weekend draws closer.
LIFR and IFR ceilings over SE Mississippi and interior SW Alabama will spread southeastward across the entire area into the early evening hours as a weak cold front pushes through the region. (Now through Tuesday Night) A weak cold front will continue to move southward across the area today as a large trough digs across the northeast states. Lows tonight will be much cooler, in the mid and upper 30s inland to low 40s along the coast. Tuesday will be dry with highs in the low 60s.
533 PM CST Mon Jan 27 2025 (This evening through Tuesday Night) Despite a passing cold front yesterday (which remains sitting offshore) and high pressure in place over the South Central CONUS, we remain fairly well saturated with lingering moisture keeping surface dew points in the mid 40s to 50s. Look for overnight lows in the upper 40s across the northern zones to the low 50s across Metro Houston and southward towards the coast. As a robust upper level low digs into the SW CONUS, 500mb analysis shows a few localized vort maxes traversing the area.
(Now through Tuesday night) Dry and mild conditions will persist as northwest flow aloft prevails between an upper longwave trough over the northeast/mid-Atlantic states and an upper ridge building over the southern/central Plains. A weak cold front currently passing through the forecast area will move entirely offshore by early evening, with some light post- frontal fog forming by late tonight, followed by decreasing clouds on Tuesday. Lows Tuesday night trend upward a bit into the lower to mid 40s most areas, with upper 40s at the beaches.
Temps should generally be able to fall into the mid to upper 30s, with some low 30s possible in our cooler spots across the northwestern forecast area.
620 PM EST Mon Jan 27 2025 - Cold Front Will Cross the Area Tuesday with a Brief Cool Down Tue Night.
Only weather concern will be fog next few nights as mostly clear skies and light winds will allow radiational cooling under a low level inversion to produce land based fog in typical fog prone areas that may advect over the cooler shelf waters and Tampa Bay. The weather pattern remains a quiet one through the rest of the week with high pressure the dominant feature. The only slight change in the line up this week will be a weak cold front moving through the area tomorrow. However, with high pressure building back in behind the front, a steady increase in temperatures continues as the weekend draws closer.
Drizzle and mist may persist through the early evening amid the low cloud ceilings.
Wrap around low clouds and perhaps some flurries or light snow showers continued in the high desert and especially mountains this afternoon. Temperatures will only slowly rebound over the next few days as the cold upper low lingers just to our east.
A slow moving upper level low will bring precipitation to portions of southern Utah through midweek.
916 PM EST Mon Jan 27 2025 A surface trof will pass through the area Tuesday.
607 PM EST Mon Jan 27 2025 (This afternoon through Tuesday) As a mid-level trough axis continues to push a frontal boundary into the southeastern United States, it will pinch high pressure back over the peninsula of Florida today.
The high pressure of 1025mb is loosely centered near Corsicana TX just to our west and will be drifting eastward during this short term over to the FL panhandle by midweek. Patchy freezing fog may also occur in a few spots as well around daybreak, so think twice about any of our northern most bridges shrouded in fog.
(This evening through Tuesday Night) Despite a passing cold front yesterday (which remains sitting offshore) and high pressure in place over the South Central CONUS, we remain fairly well saturated with lingering moisture keeping surface dew points in the mid 40s to 50s. Look for overnight lows in the upper 40s across the northern zones to the low 50s across Metro Houston and southward towards the coast. As a robust upper level low digs into the SW CONUS, 500mb analysis shows a few localized vort maxes traversing the area.
406 PM MST Mon Jan 27 2025 - Dry and mild this week with gusty winds at times - Turning colder and unsettled later this weekend 20z surface analysis had weak trough from southern MN into northwest SD, which has turned into a weak localized cold front due snow-cooled air across southeast MT/northwest SD/southwest ND.

25"+ for many coastal and valley areas, with 1-12"+ inches of snow for the higher elevations. These showers are quickly ending as the upper level low pivots eastward towards the CA/AZ border.
608 PM CST Mon Jan 27 2025 (Rest of Today) Clouds have been slow to clear north/central AL in the wake of a cold front, but high pressure moving into the region will aid in nudging this cloud deck to our south. Temperatures have remained in the low to mid 40s in most locations, with a few spots in NE AL approaching 50 degrees. Clear skies and light winds will allow for one more night below freezing as radiational cooling brings lows down to the mid to upper 20s.
340 PM MST Mon Jan 27 2025 - Dry and tranquil weather with warmer temperatures expected much of the work week.
Some patchy fog or freezing fog is possible toward Monroe County.
The combination of clear skies and calm winds has supported early development of patchy freezing fog across mainly valley locations in southern Middle TN, northeast AL and north-central AL, and an SPS has been issued to highlight the risk for a very thin glaze of ice to be deposited on elevated surfaces where fog is occurring and temperatures are at or below freezing. Neither visibilities nor coverage of freezing fog support an NPW at this point, but we will continue to monitor trends in the event that once becomes necessary early Tuesday morning as temps slowly fall into the u20s-l30s.
940 PM MST Mon Jan 27 2025 - Dry and mild this week with gusty winds at times - Turning colder and unsettled later this weekend 20z surface analysis had weak trough from southern MN into northwest SD, which has turned into a weak localized cold front due snow-cooled air across southeast MT/northwest SD/southwest ND. Main concern this forecast will be disposition of cold front for the weekend.
Patchy freezing fog, primarily in the southernmost counties of East Tennessee into southwest North Carolina, to dissipate this morning. Discussion: Clear skies in the southern Tennessee and Sequatchie valleys allowed for fog to develop overnight, and with subfreezing conditions, the potential for freezing fog and icing concerns. Otherwise clouds are expected to be scarce today, which makes it a nice day with the slightly warmer afternoon temperatures.
1111 PM CST Mon Jan 27 2025 (This evening through Tuesday Night) Despite a passing cold front yesterday (which remains sitting offshore) and high pressure in place over the South Central CONUS, we remain fairly well saturated with lingering moisture keeping surface dew points in the mid 40s to 50s. Look for overnight lows in the upper 40s across the northern zones to the low 50s across Metro Houston and southward towards the coast. As a robust upper level low digs into the SW CONUS, 500mb analysis shows a few localized vort maxes traversing the area.
259 AM EST Tue Jan 28 2025 - Breezy again today; light snow north - Mixed rain/snow and potential freezing rain late week - Breezy again today; light snow north A clipper over northern Manitoba early this morning will cross the Straits around 00z. The difference today is that the winds will be more of a warm advection wind, whereas yesterday's strongest winds will during the late afternoon and evening associated with the cold front. As the clipper goes by, the trailing cold front may produce some gusty winds late tonight especially over the eastern cwa.
The region remains under mostly clear skies this evening as a ridge of high pressure drifts south towards us.
Only a few lingering, light showers remain this evening moving from northeast to southwest in the return flow around the low pressure system which has moved east into Arizona.
Temperatures along the Island Chain are in the mid to upper 60s with dew points in the lower to mid 60s.
West winds were gusting to 25 to 45 mph (highest in EC WI) this afternoon, ahead of a strong cold front that was dropping south into Upper Michigan. Radar showed a robust line of snow showers along the cold front in southern Lake Superior.
Temperatures are going to be slow to warm up this week as the upper low that was responsible for the recent rains is only very slowly moving east.
941 PM MST Mon Jan 27 2025 - Dry and tranquil weather with warmer temperatures expected much of the work week.
1205 AM EST Tue Jan 28 2025 (This afternoon through Tuesday) As a mid-level trough axis continues to push a frontal boundary into the southeastern United States, it will pinch high pressure back over the peninsula of Florida today.
(Today) Areas of dense freezing fog have develop along the sheltered rivers valleys of northeast Alabama and portions of southern middle Tennessee. A Dense Fog Advisory for freezing fog with visibilities under 1/4 SM is in effect until 6 AM for areas generally east of I-65. Once the fog does dissipate, sunny/dry conditions are forecast underneath this ridge of high pressure.
Temperatures warm into the lower to middle 60's for most locations today, with upper 60's to lower 70's possible for the day Wednesday. Overnight lows tonight fall into the lower to middle 40's for most locations, with Wednesday night being even warmer in the upper 40's over the interior and lower to middle 50's to the south.
535 AM CST Tue Jan 28 2025 Updated at 535 AM CST Tue Jan 28 2025 - Expect sunny and warmer weather today and Wednesday.
However, for now where temperatures are below freezing and vsbys are 1/2 or below we are dealing with freezing fog which could cause slick spots on overpasses and bridges.
Surface ridging will continue keep conditions quiet Tuesday and Wednesday morning before a wet pattern returns.
618 AM EST Tue Jan 28 2025 (Today and tonight) Weak cold front moves through the region this morning with abundant low level moisture and light winds leading to conditions conducive to fog development. For this reason, have blended toward the warmer guidance for highs today, generally in the 60s across the region.
Temperatures will reach the 70s again today and knock on the door of the lower 80s in places on Wednesday afternoon.
This will lift to the northeast later today and into Wednesday as a thermal ridge brings very warm 850mb temps (up to 7C) into the Northern Plains and Upper Midwest.
This wl allow for milder air to advect into AR with aftn highs ranging fm the mid 50s to the lower 60s.
Gusty winds are expected throughout the day with the highest in the ridges.
625 AM EST Tue Jan 28 2025 Dry and warmer conditions will will develop today and Wednesday ahead of a dry cold front that will move through Wednesday night.
Upper level ridging, in the omega block fashion, is forecast through mid to late week.
Snow increases tonight and continues Wednesday as a low pressure system passes south of the region.
507 AM CST Tue Jan 28 2025 (Today) Areas of dense freezing fog have develop along the sheltered rivers valleys of northeast Alabama and portions of southern middle Tennessee. A Dense Fog Advisory for freezing fog with visibilities under 1/4 SM is in effect until 6 AM for areas generally east of I-65. Once the fog does dissipate, sunny/dry conditions are forecast underneath this ridge of high pressure.
This will place the warmer temperatures generally along and east of the I-69C corridor for today. The frontal boundary will lift northward as a warm front tonight. Lows tonight will range from the upper 50s to around 60 across the Rio Grande Plains/northern ranchlands to the low to mid 60s across the Valley and along the coast. Steady southerly flow will allow high temperatures to reach the upper 70s to the lower 80s on Wednesday.
948 AM EST Tue Jan 28 2025 Dry and warmer conditions will will develop today and Wednesday ahead of a dry cold front that will move through Wednesday night.
With the axis of the ridge overhead, sea- breeze circulations will veer wind direction onshore later today along the coast during the late morning hours into the early afternoon. Temperatures will reach the 70s again today and knock on the door of the lower 80s in places on Wednesday afternoon.
A weak boundary that developed from the offshore breeze along the Lower Keys last night helped to initiate some light shower activity over the Straits, but this line will be just offshore to the north of Cuba by the time this discussion is posted. Temperatures will once again be comfortable somewhere between the lower and mid 70s, depending on how much warm air can advect down the island chain with light, northeasterly flow. Over the course of this week, the high pressure mentioned above will nudge eastward. A deepening trough over the central U.
Patchy freezing fog, primarily in the southernmost counties of East Tennessee into southwest North Carolina, to dissipate this morning. Discussion: Clear skies in the southern Tennessee and Sequatchie valleys allowed for fog to develop overnight, and with subfreezing conditions, the potential for freezing fog and icing concerns. Otherwise clouds are expected to be scarce today, which makes it a nice day with the slightly warmer afternoon temperatures. Subtle height rises and a tad warmer temperatures aloft will translate to slightly warmer morning lows on Wednesday.
628 AM EST Tue Jan 28 2025 - Breezy again today; light snow north - Mixed rain/snow and potential freezing rain late week - Breezy again today; light snow north A clipper over northern Manitoba early this morning will cross the Straits around 00z. The difference today is that the winds will be more of a warm advection wind, whereas yesterday's strongest winds will during the late afternoon and evening associated with the cold front. As the clipper goes by, the trailing cold front may produce some gusty winds late tonight especially over the eastern cwa.
There is a 50 to 95 percent chance for freezing morning low temperatures today and Wednesday across the San Joaquin Valley.
This feature will slowly slide southeast as a weak cold front through the day as the next high pressure, centered across the Lower Mississippi Valley, slides east. High pressure over the Lower Mississippi Valley will slowly slide southeast into the Gulf of Mexico and eventually along the west coast of Florida. As this high tracks further eastward through the second half of the week, breezes will veer east to southeasterly and slowly strengthen.
