1003 PM MST Tue Jan 14 2025 - Cool, dry, and generally mild today and slightly warmer Wednesday.
1003 PM CST Tue Jan 14 2025 - Patchy blowing and drifting snow is possible tomorrow as winds pick up and warmer temperatures move into the area.
1152 PM CST Tue Jan 14 2025 (This evening through Wednesday night) Upper pattern this afternoon shows an upper trough over the Great Lakes and New England with an upper ridge off the Pacific Coast. With an upper low south of the ridge, this is producing a split flow, with our CWA primarily in the southern split. Currently, the surface pattern has high pressure across much of the Mississippi River Valley. Any rain amounts much more than about a tenth of an inch will be surprising, as there is a lot of dry air in the lower levels to overcome. Just as the lower layers get saturated, the best lift pulls away to the east. Fairly extensive cloud cover should hold temperatures above freezing across the area tonight and Wednesday night, and will likely have a negative impact on high temperatures tomorrow.
An upper level ridge will build over the area tonight and tomorrow, increasing the inversion.
Seasonable weather remains on track for tongiht, with overnight lows dipping just below freezing north of I-20 and slightly above freezing to the south. High pressure remains firmly rooted in place, ensuring calm and benign conditions in the short, with light and variable winds prevailing.
310 AM EST Wed Jan 15 2025 * After a very cold start, temperatures will struggle today, with only the snow-free areas of south central Kentucky getting above freezing.
1254 AM EST Wed Jan 15 2025 An Arctic cold front will move southeast across the region late in the day, bringing gusty winds and a quick burst of light snow. High pressure will then build into the region Wednesday.
1029 PM CST Tue Jan 14 2025 - Overnight refreezing and black ice concerns for the morning commute continue for most of the week.
Discussion: A cold front has pushed through the area in the last few hours. High pressure at the surface will be over the OH Valley today, shifting southward to the TN Valley this evening.
Breezy to locally windy northeast winds return for the coastal headland and exposed ridges this weekend. Thermal trough along the coast is promoting breezy easterly winds over the ridgetops. Low elevation temperatures are running a few to 10 degrees warmer than yesterday's reading, with dewpoints generally in the 30's. Quiet weather conditions remain across the region with a broad 500mb high pressure over the Pacific NW and Northern California, promoting dry/stable condition and interior mostly clear skies. While highs in the low to mid 50's for the coastal areas. will flatten the ridge down some on Thursday.
445 AM CST Wed Jan 15 2025 - Expect a gradual warming trend through Thursday, with highs returning to the low to upper-40s.
210 AM MST Wed Jan 15 2025 KEY MESSAGES: 1) Above normal non-freezing temps for highs will continue through Thursday. 2) The next cold front will arrive Thursday night.
536 AM CST Wed Jan 15 2025 Today and tonight: Early morning surface analysis had a >1036mb high centered over the mid Mississippi river valley, a nearly stationary dry cold front across northern Mississippi and an inverted trough over the western Gulf south of Brownsville. The inverted trough will deepen and help develop convection that will spread northeast along the Gulf coast and near our southern most zones this evening. Model consensus is that very low pops of light rain will be carried across our southern most zones tonight and this chance of light rain will end long before temperatures come close to freezing. Otherwise, together these features will result in slightly warmer highs this afternoon than yesterday but slightly cooler morning lows Thursday than wl see this morning.
High pressure remains generally in control although some returns are showing up on radar this morning. Rain chances will be on the lower side with this system and not expecting much in the way of rainfall amounts either.
Similar conditions will continue through the week, as our upper level pattern remains firmly controlled by ridging in the Eastern Pacific. A closed low remains in place off the coast of SoCal, as well as the 500mb high pressure off NorCal's coast.
There is small potential (less than 10 percent chance) for some freezing drizzle.
549 AM CST Wed Jan 15 2025 - Increasing chances for light snow and freezing drizzle north of I-94 this afternoon and evening.
Dry weather will prevail through the majority of the week into the weekend as high pressure builds across the Pacific Northwest. Cold overnight temperatures this week with inland temperatures near freezing, producing frosty mornings in locations that don't have stratus overhead.
202 AM PST Wed Jan 15 2025 * High pressure will dominate the pattern through midweek, maintaining lighter winds and persistent valley inversions. * A dry cold front this weekend will bring gusty northeast ridge winds and colder temperatures. Current Conditions Through Midweek: * High pressure is strengthening over the region, creating a dry and stable airmass. Northeast ridge winds will persist through this morning, with gusts of 40-50 mph along exposed ridges easing by afternoon. Valley inversions will trap cold air at lower elevations, resulting in overnight temperatures below freezing in sheltered valleys and daytime highs in the 40s to low-50s.
Widespread freezing temperatures are forecast across mainly rural areas of the San Joaquin Valley again this morning.
This is a degree to two warmer than the previous forecast.
630 AM EST Wed Jan 15 2025 * After a very cold start, temperatures will struggle today, with only the snow-free areas of south central Kentucky getting above freezing.
523 AM CST Wed Jan 15 2025 (Today through Thursday) A surface cold front is currently across far northern Alabama will approach from the north during the day on Wednesday, but is expected to stall over northern Alabama. High pressure briefly builds in on Thursday in advance of the next approaching cold front. A few degrees warmer on Thursday with a little bit more sunshine.
532 AM CST Wed Jan 15 2025 - Expect a gradual warming trend through Thursday, with highs returning to the low to upper-40s.
Overall it looks like a partly to mostly cloudy day with temperatures climbing into the lower 60s north to lower 70s south.
305 AM CST Wed Jan 15 2025 Today and tonight: Early morning surface analysis had a >1036mb high centered over the mid Mississippi river valley, a nearly stationary dry cold front across northern Mississippi and an inverted trough over the western Gulf south of Brownsville. The inverted trough will deepen and help develop convection that will spread northeast along the Gulf coast and near our southern most zones this evening. Model consensus is that very low pops of light rain will be carried across our southern most zones tonight and this chance of light rain will end long before temperatures come close to freezing. Otherwise, together these features will result in slightly warmer highs this afternoon than yesterday but slightly cooler morning lows Thursday than wl see this morning.
Despite this, it will still be a chilly start across the Bay Area and Central Coast with temperatures dropping into the upper 30s and low 40s across the Bay Area, and down to the low 30s across inland portions of the Central Coast.
An area of low pressure along the coast is producing northeasterly winds across the eastern half of our CWA. This low will drift toward the east today. This area of rain will move away as the low moves farther into the Gulf, and all rain chances will end by mid-afternoon. Look for overnight lows to be cooler than today in the lower 30s to lower 40s. Some of the colder spots in the Hill Country may drop to freezing.
615 AM EST Wed Jan 15 2025 (Today through Thursday) A broad area of high pressure extending across much of the southeastern US will build over South Florida today, allowing for benign sensible weather. Winds veer from the east/northeast on Thursday as the high continues to expand, all the while the pressure gradient eases up across the region.
/EC/ Today and tonight: Early morning surface analysis had a >1036mb high centered over the mid Mississippi river valley, a nearly stationary dry cold front across northern Mississippi and an inverted trough over the western Gulf south of Brownsville. The inverted trough will deepen and help develop convection that will spread northeast along the Gulf coast and near our southern most zones this evening. Model consensus is that very low pops of light rain will be carried across our southern most zones tonight and this chance of light rain will end long before temperatures come close to freezing. Otherwise, together these features will result in slightly warmer highs this afternoon than yesterday but slightly cooler morning lows Thursday than wl see this morning.
Temperatures have managed to warm into the lower 70s and dew points have held in the lower 60s, making for a pleasant day. A high pressure spilling into the Mid-Atlantic and Southeast U. Meanwhile, an elongated baroclinic zone extends from just offshore of central Florida and across the Gulf of Mexico (GOM) to an inverted trough in the far western GOM.
400 PM EST Wed Jan 15 2025 High pressure will build in tonight and crest over the area early Thursday. The high will east move through the Canadian Maritimes later Thursday.
Dry and cool conditions will continue in the short term forecast as a persistent upper level Eastern Pacific ridge remain in place.
Have adjusted high temperatures down a degree based on current temperatures and trends behind the overnight cold front that is now over southern Georgia. Otherwise cold high pressure over the Ohio Valley will move southeast across the eastern Tennessee Valley during the day today. Discussion: A cold front has pushed through the area in the last few hours. High pressure at the surface will be over the OH Valley today, shifting southward to the TN Valley this evening.
A slight offshore gradient still exists where the mean flow is easterly due to lingering high pressure over the Great Basin and a nearly stationary upper low well off the coast of Baja. This pattern continues tomorrow before the upper low finally starts to move inland.
1131 AM CST Wed Jan 15 2025 - Expect a gradual warming trend through Thursday, with highs returning to the low to upper-40s.
Temperatures are on the cooler side but rebounding quickly. Breezes will further slacken and eventually clock around to the southeast and south as a series of high pressures move across the southeastern U.
(Rest of today through Thursday) A broad area of high pressure extending across much of the southeastern US will build over South Florida today, allowing for benign sensible weather through the period. Winds veer from the east/northeast on Thursday as the high continues to expand, all the while the pressure gradient eases up across the region leading to very weak to non-existent surface movement across South Florida.
Highs Thursday with flattening upper level ridge pushing east mainly in the 30s with some 20s in the Upper Snake Plain and Highlands.
202 PM CST Wed Jan 15 2025 - Few flurries/freezing sprinkles possible north and east.
Low pressure will bring milder temperatures and rain chances back to the Carolinas for the weekend.
933 AM MST Wed Jan 15 2025 KEY MESSAGES: 1) Above normal non-freezing temps for highs will continue through Thursday. 2) The next cold front will arrive Thursday night.
202 PM CST Wed Jan 15 2025 - Light snow with some possible patchy freezing drizzle should move off through the evening leaving scattered flurries into Thursday morning.
243 PM CST Wed Jan 15 2025 - Temperatures trend warmer through the end of the week.
Warmer temperatures than earlier this week, but still relatively cold.
412 PM MST Wed Jan 15 2025 - Slightly warmer conditions are on the way as high pressure builds over the area. The exception will continue to be the high snow covered valleys where cold air remains trapped and cold temperatures will persist.
202 PM MST Wed Jan 15 2025 KEY MESSAGES: 1) Above normal non-freezing temps for highs will continue through Thursday. 2) The next cold front will arrive Thursday night.
603 PM CST Wed Jan 15 2025 - Light snow with some possible patchy freezing drizzle should move off through the evening leaving scattered flurries into Thursday morning.
- Few flurries/freezing sprinkles possible north and east.
541 PM CST Wed Jan 15 2025 - Temperatures trend warmer through the end of the week.
646 PM EST Wed Jan 15 2025 High pressure will build in tonight and crest over the area early Thursday. The high will east move through the Canadian Maritimes later Thursday.
434 PM MST Wed Jan 15 2025 - Cool, dry, and generally mild today and slightly warmer Thursday.
Therefore, we should see more of the same later tonight with more dense fog and freezing fog. Temperatures might trend a few degrees warmer compared to last night, although freezing fog remains more likely in the Rogue and Illinois Valleys with dense fog in the Umpqua Valley. We opted not to go with another dense fog and freezing fog advisory as the inversion shouldn't be as strong, although visibilities should be hovering around 1/4 a mile for most of the night. Afternoon high temperatures might trend lower in a few locations as the ridge is not as strong Thursday afternoon.
233 PM MST Wed Jan 15 2025 - Cool, dry, and generally mild today and slightly warmer Thursday.
256 PM MST Wed Jan 15 2025 - Slightly warmer conditions are on the way as high pressure builds over the area. The exception will continue to be the high snow covered valleys where cold air remains trapped and cold temperatures will persist.
951 PM EST Wed Jan 15 2025 High pressure will build in tonight and crest over the area early Thursday. The high will east move through the Canadian Maritimes later Thursday.
Persisting cloud cover will act to moderate overnight lows as well afternoon highs in affected areas, with lows in the mid 40s north to mid 50s south, and highs in the lower 60s north to upper 60s south.
The weather pattern continues to remain stagnant in a Rex Block- like pattern this afternoon, with a weak cutoff low offshore in the eastern Pacific and amplified ridging stacked above the low generally across the West Coast. Heading into late week, a pattern transition will bring cooler and possibly wetter conditions to the region. A potent Arctic trough will descend from the Gulf of Alaska southeastward tonight, which will mark the end of the Rex Block- type pattern going into tomorrow as the ridging pattern will weaken and slide east of the Rockies. This change in pattern will bring in cooler temperatures and marginal precipitation chances for south-central Arizona.
Gusty northerly and northeasterly breezes are expected to return for the coastal headlands and exposed ridges this weekend.
1033 PM EST Wed Jan 15 2025 A moderating westerly flow of air will return temperatures to around normal for Thursday and Friday as high pressure keeps us dry.
1113 PM CST Wed Jan 15 2025 - Above-freezing temperatures are forecast Thursday and Friday afternoons, leading to some melting of the snowpack across the region.
1253 AM MST Thu Jan 16 2025 The ridge of high pressure overhead will slowly begin to erode throughout the day today as we start to feel the influence of an upper level trough that will swing through the region during the day on Friday. Despite the high pressure eroding, today looks generally pleasant with ample sunshine expected and temperatures on the warmer side of normal, albeit still chilly. Clouds will begin increasing around sunset tonight along the Idaho/Montana border as the aforementioned upper level trough dips down into the CONUS from western Canada. As the trough digs into the region, snow chances increase for much of the area although this system lacks deep moisture given its polar origins so not expecting any significant snowfall.
At the sfc, ridging to the northeast will sink south then eastward from Thu-Fri. Some rain chances will be in the forecast Friday afternoon and evening as the next H500 system nears the state and a cold front approaches.
1136 PM EST Wed Jan 15 2025 High pressure will build in tonight and crest over the area early Thursday. The high will east move through the Canadian Maritimes later Thursday.
A cold front along with cold air advection aloft will improve mixing on Friday. High pressure will remain in control through late Thursday, setting the stage for strengthening inversions at the surface and aloft. Sounding data indicates the ridge-based inversion tops out close to 1200 ft MSL. There is good agreement that a cold front will work through the region overnight Thursday into Friday and work to eliminate the inversion. Along with the frontal system, mid and upper level winds will channel cooler and drier air from the north into the region. NBM guidance indicates less than a 20% chance of more than 2 inches of snowfall for the highest peaks of central Idaho.
A low amplitude mid-level ridge is moving over Texas this morning. Increasing mid and upper level cloud cover tonight along with a return of southerly flow in the low-levels will yield overnight lows mainly in the 40s. Highs will be around five degrees warmer than today.
1141 PM CST Wed Jan 15 2025 - Temperatures trend warmer through the end of the week. - Rain moves through Friday night, ahead of an Arctic cold front that may bring in the coldest air this winter behind it.
Updated at 214 AM CST Thu Jan 16 2025 - Cold front arrives tomorrow - very warm ahead of it, and much colder behind it.
(Today through Friday) Models and sfc analyses show a weakening ridge still lingering over the SE CONUS, while a low pressure system in the western GOMEX gradually migrates SE through Friday. Meanwhile, low-level flow winds will gradually shift to a more E-ENE flow today as the aforementioned ridge continues to expand.
- A short-lived warming trend begins tonight through the end of the work week, with highs reaching the low 40s on Friday.
Lows will be seasonable, falling near freezing areawide (29-35F).
1024 PM MST Wed Jan 15 2025 - Cool, dry, and generally mild today and slightly warmer Thursday.
Warming trend peaks Thursday as high pressure associated with a blocking pattern passes over the State.
- Thursday and Friday will be warmer with highs in the low to mid 30s.
Low pressure over the Pacific will start to move towards the Baja coast, continuing to move towards the northeast through the day. As the low crosses Arizona, it begins to weaken and opens up into more of a wave, quickly exiting the region on Friday. Best chances remain across central Arizona, with 20-30% chances over the higher terrain of the Bradshaw Mountains, along the Mogollon Rim, and into the White Mountains. Cold air doesn't really arrive behind the low so expect temperatures to remain near to slightly below normal through the weekend.
There is some question on the timing of the cold front which would likely have an impact on the temperature forecast for Friday.
High pressure and dry weather finally returns on Friday, but another system brings a mix of rain and snow to the area this weekend. Although this system looks to be pretty moisture starved, with temperatures topping out in the low to mid 20s, SLR ratios will still be relatively high, resulting in a fresh fluffy coating to an inch or two of accumulation, mainly west of I-81. High pressure will build into the region Friday which looks to shut off any lake effect snow. Most spots should get into the low 30's. Clouds though are quickly on the increase Friday night ahead of a cold frontal boundary.
248 AM CST Thu Jan 16 2025 - Warmer today and into Friday with highs in the mid 30s to mid 40s.
Confidence in the stratus deck remaining through the overnight hours is high (80%) A special weather statement for patchy freezing fog has been issued for the foothills of the Blue Mountains of WA and OR, especially along HWY 11 between Athena and Walla Walla and along portions of the I-84 corridor between Cabbage Hill and Mission. A strong ridge of high pressure over the Pacific Northwest will break down this evening into tonight as a weak trough and cold front approach generally to the north. Patchy dense fog and freezing fog continue across the Blue Mountain Foothills and are expected to linger into tonight before improvement arrives on Thursday. Additional freezing fog is possible overnight, especially across the Columbia Basin and other low lying areas.
Stable post cold front conditions continue and no precipitation has been detected. Short Term Update - The surface pressure ridge will settle further southeastward through the overnight period. This along with night time cooling and cooler waters will likely result in winds backing northeasterly while continuing to trend slightly downwards. Rain chances will remain nil due to the continued relatively dry post cold front environment. Ridging across the southern states will be pressed southeastward overnight by a mid latitude low swinging into the northeast. As the ridge axis moves southeastward into Florida, along with cooler waters, and mainland cooling will result in waters nearer the peninsula tending to remain northeasterly.
1221 AM EST Thu Jan 16 2025 A moderating westerly flow of air will return temperatures to around normal for Thursday and Friday as high pressure keeps us dry.
We will see cooler highs with 40s over the snowpack across the eastern zones. Do expect cooler highs with 50s west to 40s east.
Although radar has indicated a few very light showers, mainly over southwest Florida, atmosphere in the low levels is very dry and any rain aloft is evaporating before hitting the ground. The two streams will come in-phase creating a high amplitude pattern across the entire CONUS, carving out a deep extensive L/W trough from Hudson Bay through the plains states. Trailing will be a sharp U/L ridge off the west coast of the U. Along the leading edge of the cold air, an area of low pressure will develop and move across the Lower Mississippi Valley Friday night. Return flow will develop over the Florida peninsula advecting warmer much moister air across the forecast area.
High pressure and dry weather finally returns on Friday, but another system brings a mix of rain and snow to the area this weekend. Temperatures this afternoon only top out in the low to mid 20s, so even though QPF is only around 0. Brief high pressure will settle over the region on Friday, however some lake effect flurries will still be possible north of the NYS Thruway. Highs on Friday will climb into the low to mid 30s for most of the area. High pressure will build into the region Friday which looks to shut off any lake effect snow. Most spots should get into the low 30's. Clouds though are quickly on the increase Friday night ahead of a cold frontal boundary.
1034 PM CST Wed Jan 15 2025 -Warmer weather is expected in the near future, with all of northeast KS likely experiencing temps in the 40's on Friday.
208 AM CST Thu Jan 16 2025 - Patchy freezing fog remains a possibility late tonight in areas south of a Macomb to Danville line, though forecast confidence is below 50%.
919 PM MST Wed Jan 15 2025 - Slightly warmer conditions are on the way as high pressure builds over the area. The exception will continue to be the high snow covered valleys where cold air remains trapped and cold temperatures will persist.
Rain chances will taper off overnight as a weak system moves out and high pressure builds in.
- Windy conditions expected for Friday, followed by a strong cold frontal passage Friday night. As we go throughout the day, winds will slowly turn to the south as the high slides off to the southeast. Aloft, we'll see upper level ridging build in as a trough moves over the eastern U. Warm air advection, upper ridging, and a few hours of sunshine will raise temperatures by a few degrees this afternoon, putting highs in the lower 60s. As the upper low moves over the southwestern U. Temperatures tonight will be much warmer, with lows staying in the 40s for much of the area.
