606 AM EST Wed Nov 19 2025 - An area of low pressure and its trailing cold front will track through the Ohio Valley and bring widespread rain chances to the region early this morning. Widespread low clouds and fog have developed this morning in the wake of overnight rain and the passage of a weak cold front. Increasing mid-level geopotential heights this morning through tonight with near-surface weak cold advection and a moist air mass behind a weak cold front will mean widespread low stratus with fog development this morning, with widespread stratus that is expected to persist through much if not all of the daytime hours and into the nighttime hours tonight.
556 AM EST Wed Nov 19 2025 Low pressure to our south this morning gives way to high pressure building in from the west for the rest of the day.
A low pressure system will cross the region over the next several days bringing cooler temperatures, chances for precipitation including snowfall above 7000 feet, and breezy conditions.
High temperatures today will reach the lower 80s along the coastline, with mid to upper 80s possible for portions of interior South Florida.
938 AM EST Wed Nov 19 2025 Low pressure to our south this morning gives way to high pressure building in from the west for the rest of the day.
Otherwise, ample sunshine should allow temperatures to climb into the lower 80s again this afternoon.
Yesterday's weather across the Keys was a bit abnormal thanks to a weak low pressure system located over western Cuba. Thick layers of cloud cover generated by the low persisted throughout the day over the Lower Keys and the Florida Straits. Currently, showers generated by the low are lingering over the southwestern Straits of Florida as highlighted by the KBYX radar. A well established ridge is centered from the Yucatan to Minnesota, and that ridge will trap a sequence of cutoff lows over the western half of the country.
657 AM EST Wed Nov 19 2025 Dry weather returns through Thursday with building high pressure.
637 AM EST Wed Nov 19 2025 Low pressure passing by to the south will bring some light rain and high elevation snow to NE PA early this morning.
546 AM EST Wed Nov 19 2025 - An area of low pressure and its trailing cold front will track through the Ohio Valley and bring widespread rain chances to the region early this morning. Widespread low clouds and fog have developed this morning in the wake of overnight rain and the passage of a weak cold front. Increasing mid-level geopotential heights this morning through tonight with near-surface weak cold advection and a moist air mass behind a weak cold front will mean widespread low stratus with fog development this morning, with widespread stratus that is expected to persist through much if not all of the daytime hours and into the nighttime hours tonight.
726 AM EST Wed Nov 19 2025 - Cloudy skies with patchy light rain and drizzle linger today behind this morning's weak cold front passage. Widespread low clouds and fog have developed this morning in the wake of overnight rain and the passage of a weak cold front. Increasing mid-level geopotential heights this morning through tonight with near-surface weak cold advection and a moist air mass behind a weak cold front will mean widespread low stratus with fog development this morning, with widespread stratus that is expected to persist through much if not all of the daytime hours and into the nighttime hours tonight.
- Warmer than normal temperatures continue. By Wednesday afternoon, the upper low begins shifting east across the Desert Southwest and northern Mexico, providing enough large-scale ascent to support isolated to scattered showers across portions of the region. As the upper low elongates Wednesday night into Thursday, forcing for ascent increases across the state.
Otherwise, another beautiful day across the region with plenty of sunshine and warm temps in the low to mid 80s this afternoon. High temperatures today will reach the lower 80s along the coastline, with mid to upper 80s possible for portions of interior South Florida.
The low pressure system causing all this ruckus is currently center just off the southern California Coast. The totals across Yavapai County and lower elevation locations are strictly from rainfall, but a few areas across the High Country also include melted snowfall.
The upper low responsible for our stormy and cold weather the past couple of days is shifting slowly eastward into Arizona this afternoon. A very moist southerly flow, combined with large scale lift associated with the low continues to result in widespread rain and snow showers with isolated thunderstorms. As the low shifts eastward through the overnight hours into Thursday, the eastern part of the state should see the brunt of the precip with 0.
Through Thursday: Mid afternoon satellite imagery/RAP analysis showed the circulation around a closed low over southern California and ridging from the Gulf across our CWA and over the mid Mississippi valley. A disturbance rounding the base of the closed low will track northeast across the southern Plains tonight and then over the upper level ridge Thursday. Surface ridging across the Gulf coast and ridging aloft will try to hang tough over our CWA but model consensus suggests low rain chances will return to our northwest most zones by sunrise and then continue along and north of Highway 82 Thursday as the disturbance moves east and well to our north.
There is some lingering low stratus that will likely hang around most of the day until a cold front moves the low stratus out of the area tonight. Most models and recent model runs favor a more northern track that would keep the highest impacts in Canada, though a more southern track that could produce winter weather impacts over the state definitely remains plausible as well. KXWA is impacted from this low stratus and fog that lingers across the northwest.
Becoming cooler as we start to approach Thanksgiving. Radar returns are showing some light showers across these areas as well with snow levels continuing to run around 7000 ft leaving any winter weather impacts to the highest terrain and mountain passes. As has been the case for much of this month, lows tonight will remain on the warmer side of normal overnight and into Thu morning.
1218 PM EST Wed Nov 19 2025 Low pressure to our south and east pushes away and gives way to high pressure building in from the west for the rest of the day.
There is some lingering low stratus that will likely hang around most of the day until a cold front moves the low stratus out of the area tonight. Most models and recent model runs favor a more northern track that would keep the highest impacts in Canada, though a more southern track that could produce winter weather impacts over the state definitely remains plausible as well.
The forecast remains on track this morning with temperatures already hovering in the low 80s throughout the island chain. High pressure stretching from the western Atlantic to the Florida panhandle will lead to easterly to northeasterly breezes across the Florida Keys coastal waters. The high gradually weakens during the second half of the week, which will allow breezes to slacken from moderate or fresh to gentle by the weekend.
1209 PM CST Wed Nov 19 2025 - Potentially wetting rains and cooler temperatures will arrive to the Panhandles starting Wed night through Thu. (Tonight through Thursday night) Moisture is (knock knock) knocking on the Panhandles' door today, gradually streaming in ahead of the approaching closed low currently passing over southern California. The first wave of energy ahead of the low should get to the Panhandles later this morning and afternoon, and may be enough to generate some scattered light showers, with perhaps a few weak storms over eastern counties based on recent CAM runs (15-30% POPs).
259 PM EST Wed Nov 19 2025 - Light rain with some snow mixing in for the high elevations tracks west to east tonight through Thursday. Snow may briefly mix in at times as temperatures cool tonight just below freezing, mainly in the higher elevation areas.
- A low chance for rain or drizzle Thursday night along and behind a cold front. - High pressure will move into the region for the beginning of the weekend with highs in the low 50s. Model data supports the center of high pressure passing eastward this evening eventually allowing some semblance of weak southerly return flow.
North Pacific cold front near 130W this morning will move onshore late today and as far inland as eastern OR overnight, then dissipate in western ID Thursday morning.
The forecast remains on track this morning with temperatures already hovering in the low 80s throughout the island chain. From synopsis, a high pressure system stretching from the western Atlantic to the Florida panhandle will sustain northeast to east breezes across the Florida Keys coastal waters. Expect the high to gradually weaken during the second half of the week, which will allow breezes to slacken from moderate or fresh to gentle by the weekend.
CAPE profiles today remain abysmally low in the High Plains; therefore, thunderstorm chances remain on the fringes of possibility this afternoon and evening. This may be due to the lower confidence for embedded thunderstorms during the day, and the decrease in coverage amongst the CAMs compared to the global models.
Some patchy drizzle may be falling at times form the low clouds/status and reduced visibilities still remain on ridges from stratus build down. Locations in the north should reach the low to mid 50s while near the TN border along/south of the boundary should reach the mid to upper 60s. Widespread low clouds and fog have developed this morning in the wake of overnight rain and the passage of a weak cold front. Increasing mid-level geopotential heights this morning through tonight with near-surface weak cold advection and a moist air mass behind a weak cold front will mean widespread low stratus with fog development this morning, with widespread stratus that is expected to persist through much if not all of the daytime hours and into the nighttime hours tonight.
124 PM EST Wed Nov 19 2025 A weak cold front will drop south into this evening bringing relatively cooler weather for Thursday.
1137 AM CST Wed Nov 19 2025 - Areas of dense fog this morning in Western Wisconsin, with below freezing temperatures this freezing fog could lead to slick spots on untreated roads and surfaces. With the cool temperatures this is a freezing fog which could lead to slick spots on untreated roads and surfaces this morning. Farther to the west over Minnesota cloud cover is keeping temperatures warmer and dense fog is not expected. With temperatures staying above freezing tonight no impacts are expected.
1142 AM EST Wed Nov 19 2025 Low pressure to our south and east pushes away and gives way to high pressure building in from the west for the rest of the day.
High temperatures are forecast to warm into the 40s to lower 50s ahead of a weak cold front. High temperatures tomorrow are forecast to be on the cooler side in the upper 30s to mid 40s as a cold front moves through the region tonight.
151 PM CST Wed Nov 19 2025 - Patchy drizzle and fog overnight, but surface temperatures will remain above freezing so no impacts from icing expected.
1223 PM EST Wed Nov 19 2025 Low pressure passing by to the south will bring some light rain and high elevation snow to NE PA early this morning.
The low clouds allowed temperatures to remain above freezing for the interior valleys. Thursday morning, the high res radar reflectivity shows most of the precipitation confined to east of the Cascades, with post frontal showers along the coast and coastal counties, with a general downward trend in radar returns as the morning progresses. The afternoon could end up dry for most locations as the upper low splits from the main flow and moves south into northern California.
- A low chance for rain or drizzle Thursday night along and behind a cold front. - High pressure will move into the region for the beginning of the weekend with highs in the low 50s. High pressure centered right over the Great Lakes has maintained mostly clear skies, with high-based cirrus now streaming in from the west. Wind direction will veer southeasterly and eventually southerly as high pressure departs the region. Fairly quiet forecast for the week as a split flow pattern keeps the strongest northern stream flow up across Canada while the weaker southern stream is steered by a cutoff upper low over the SW conus and held mainly south of the region.
944 AM PST Wed Nov 19 2025 Light rain/snow showers over the highest points of the mountains today before drier weather tonight into Thursday morning.
Clouds will slowly scatter by noon and allow temperatures to top out well above normal again, in the lower 80s.
In the upper levels we remain dominated under an elongated ridge that extends from the Hudson Bay into the Bay of Campeche. Across southern California an upper level low situated in the base of a digging trough is attempting to move further east. In the short term, the ridge will hold in place and steer this next system up and over into the Ohio Valley. At the same time, it will act to temporarily flatten the ridge and shift southward across the Gulf Basin for the weekend.
143 PM EST Wed Nov 19 2025 High pressure in place and mostly clear skies this evening will make for a cold night.
- A low chance for rain or drizzle Thursday night along and behind a cold front. - High pressure will move into the region for the beginning of the weekend with highs in the low 50s. Mainly clear skies outside of some thickening cirrus for the late evening period, as high pressure maintains control. Light southerly flow will emerge upstream overnight as the high slides east, effectively drawing existing low level moisture to the southwest back into the region overnight and Thursday morning. Expectation for this low stratus to hold through the remainder of the taf period, with some fluctation in cloud base on either side of 2000 ft. Model data supports the center of high pressure passing eastward this evening eventually allowing some semblance of weak southerly return flow.
Generally 1-6" of snow is expected with the highest amounts in the Front Range Mountains.
Cooler than normal temperatures will continue through the work week.
531 PM CST Wed Nov 19 2025 - Rain and drizzle mixed with areas of freezing drizzle and snow continue overnight into Thursday morning.
621 PM EST Wed Nov 19 2025 High pressure in place and mostly clear skies this evening will make for a cold night.
/NF/ Through Thursday: Mid afternoon satellite imagery/RAP analysis showed the circulation around a closed low over southern California and ridging from the Gulf across our CWA and over the mid Mississippi valley. A disturbance rounding the base of the closed low will track northeast across the southern Plains tonight and then over the upper level ridge Thursday. Surface ridging across the Gulf coast and ridging aloft will try to hang tough over our CWA but model consensus suggests low rain chances will return to our northwest most zones by sunrise and then continue along and north of Highway 82 Thursday as the disturbance moves east and well to our north.
634 PM EST Wed Nov 19 2025 A weak cold front will move south of the area this evening bringing cooler temperatures Thursday.
Issued 305 PM CST Wed Nov 19 2025 Tonight through Thursday night: As high pressure exits the Great Lakes region eastward Tonight through Thursday, mostly dry and quiet weather is expected. Low clouds linger into Thursday, with the aforementioned southwest breeze boosting high temps to the low 50s (around 6 to 10 degrees above seasonal norms). 10-20% precip chances are included for the majority of the region on account of the low stratus producing some drizzle, models allow for only a few hundredths of an inch liquid precip (if anything at all) on Thursday. Forecast soundings indicate the moisture / saturation extends through only the lowest 5000 ft AGL of the atmosphere (to the 850mb level at best), gradually drying out Thursday night.
Temperatures will be cooler, but still above normal through the week. Some potential for fog/freezing fog development overnight, primarily across favored valleys of eastern WA and northern ID.
306 PM CST Wed Nov 19 2025 - Rain and drizzle mixed with areas of freezing drizzle and snow continue overnight into Thursday morning.
Widespread cloud cover remains over the area with clearing starting to show up late tonight into tomorrow as high pressure works its way in. High temperatures are forecast to warm into the 40s to lower 50s ahead of a weak cold front. High temperatures tomorrow are forecast to be on the cooler side in the upper 30s to mid 40s as a cold front moves through the region tonight.
From synopsis, a high pressure system stretching from the western Atlantic to the Florida panhandle will sustain northeast to east breezes across the Florida Keys coastal waters. The high will gradually weaken during the second half of the week, which will allow gentle to moderate breezes to briefly slacken to light to gentle by the weekend.
508 PM CST Wed Nov 19 2025 - Patchy drizzle and fog overnight, but surface temperatures will remain above freezing so no impacts from icing expected.
643 PM EST Wed Nov 19 2025 - Light rain with some snow mixing in for the high elevations tracks west to east tonight through Thursday. Snow may briefly mix in at times as temperatures cool tonight just below freezing, mainly in the higher elevation areas.
The temps (and some road temps) have chilled to or even below freezing. As noted the last few days, the fast northern jet will push a cold front across the area rather quickly on Friday, with limited shower activity.
The warm front causing this rain will move north Thursday night into Friday which will cause the rain to overspread the entire area. Increasing low level southerly flow ahead of a low developing over the Plains will push a warm front from Arkansas late tonight into Thursday. Guidance is showing weak to moderate low level moisture convergence overspreading much of southern Missouri area ahead of the warm front late tonight into Thursday morning. Persistent southerly flow will continue to push the warm front north to near the Missouri/Iowa border Thursday night. Low level flow turns more westerly just ahead of the low which shuts off much of the moisture convergence and finally brings an end to the rain. Temperatures south of the warm front on Thursday and Friday will be milder than today, mainly in the upper 50s and 60s.
214 AM EST Thu Nov 20 2025 High pressure will cross the region today through early Friday.
Additional deformation precipitation is likely into Friday as the midlevel level trough progresses into the MS valley. Midlevel ridging will slide into the central/southern Plains throughout the weekend with mostly sunny skies and seasonable temperatures in the 50s to near 60 expected.
1059 PM CST Wed Nov 19 2025 - Rain returns starting tonight through Friday with the higher rainfall totals trending towards central Missouri. - Conditions trending cooler for the second half of the work- week, nearing seasonal averages by Friday with highs ranging in the 50s to low 60s.
The highest rainfall totals expected with this next event will be south of a Quincy to Terre Haute line where there is currently a high (50-80%) chance of exceeding 0.
333 AM EST Thu Nov 20 2025 High pressure remains in control through Friday.
239 AM EST Thu Nov 20 2025 High pressure will be pushed to the east today as a cold front approaches the northern Great Lakes.
1215 AM EST Thu Nov 20 2025 - Mainly cloudy through the remainder of the week with highs in the mid 40s today, and the low-mid 50s for Thursday and Friday.
1144 PM CST Wed Nov 19 2025 - Patchy drizzle and fog overnight, but surface temperatures will remain above freezing so no impacts from icing expected.
104 AM EST Thu Nov 20 2025 High pressure will move off to the east, although clouds will be stubborn. Rain will spread back into the area late tonight and continue into Friday night as an area of low pressure moves through the region. High pressure will build in for the weekend. Short wave lifting into the central Plains tonight will then slide east in confluent flow between a northern stream low tracking across eastern Canada and broad southern stream ridging along the Gulf. Warm front out ahead of the low will lift into the area on Friday.
1259 AM EST Thu Nov 20 2025 High pressure remains in control through Friday.
1243 AM EST Thu Nov 20 2025 High pressure in place and mostly clear skies this evening will make for a cold night. Clouds stream in late tonight into tomorrow ahead of a cold front that passes through Thursday night into Friday. Some high clouds start to advect into the region from the west as the upper level ridge flattens out and subtle warm air advection begins aloft.
UPDATE Widespread cloud cover remains over the area with clearing starting to show up late tonight into tomorrow as high pressure works its way in. High temperatures are forecast to warm into the 40s to lower 50s ahead of a weak cold front. High temperatures tomorrow are forecast to be on the cooler side in the upper 30s to mid 40s as a cold front moves through the region tonight. An upper level ridge is forecast to amplify and progress across the Northern Rockies into the Northern Plains Thursday into Friday.
1258 AM EST Thu Nov 20 2025 High pressure remains in control through Friday.
313 AM EST Thu Nov 20 2025 A cold front will settle across GA and SC today. High pressure will ridge across the region for Thursday through early Friday before the front lifts north as a warm front on Friday across the Carolinas and into VA. Sfc analysis this morning depicted nely flow across central NC in wake of a cold front that has cleared south into SC/GA. With the front stalled to our south, and persistent nely flow, expect highs today to be a bit cooler in the upper 50s (NE) to around 70 (SW). The front previously stalled across SC on Thursday will move north as a warm front on Friday.
Much of the stratus coverage has become disrupted in far southwest Idaho due to isolated showers and mid level clouds this evening ahead of the next low pressure system. As the upper low approaches from the west, a broader swath of precip will arrive with an occluded surface front around mid morning. Momentum of this precip band will slow and stall in east OR and far southwest ID once the upper low dives south into California and Nevada.
Building high pressure will dry bring dry weather, above average interior daytime highs, and chilly overnight lows.
1152 PM CST Wed Nov 19 2025 - Rain and drizzle mixed with areas of freezing drizzle and snow continue overnight into Thursday morning.
Becoming cooler as we start to approach Thanksgiving. Radar returns are showing some light showers across these areas as well with snow levels continuing to run around 7000 ft leaving any winter weather impacts to the highest terrain and mountain passes. As has been the case for much of this month, lows tonight will remain on the warmer side of normal overnight and into Thu morning. By Friday, an area of low pressure will be situated over southern California.
127 AM EST Thu Nov 20 2025 Dry weather will continue today, before low pressure tracks across James Bay bringing some light rain late Thursday night and Friday. Milder air out ahead of this system will give way to more seasonable temperatures later Friday and Friday night following the passage of its trailing cold front, with high pressure then building across our region this weekend and providing us with mainly dry weather and continued seasonable temperatures. Our gradual warming trend will continue, with highs in the mid and upper 40s, but cooler east of Lake Ontario. Low pressure will slide from lower Hudson Bay to central Quebec Friday while sending an attendant cold front through western and northcentral NY. Cold front settles south of the region Friday night with a cooler airmass moving into the region in the wake of the fropa.
957 PM MST Wed Nov 19 2025 - An incoming system will bring snow to the mountain peaks and rain showers to the lower elevations, through Friday morning.
