- A cold front will move through the region during the first half of the day Wednesday with a 20-50% chance of brief showers along it. - Breezy, cooler and drier conditions forecast behind the front with a light freeze forecast across the Hill Country Thursday morning One more night of unseasonably warm and humid conditions across south-central Texas. The cold front is on track to move through the Hill Country and southern Edwards Plateau between 6-9a Wednesday, the northern Rio Grande and I-35 corridor 9a-12p, and Coastal Plains 11a-2p.
Winds diminish gradually during the day Thursday as a ridge moves over the region. Temperatures are forecast to warm up as a result of this ridge with well above normal highs expected for the second half of the week.
400 AM EST Wed Dec 18 2024 A low pressure system will move northeast into our region today bringing a round of rain ending as snow showers.
Guidance has trended a degree warmer or so for today, along with a faster arrival time of precipitation. Snow will be tapering towards the higher elevations pre-dawn Thursday.
- Temperatures will be warmer than average to much warmer than average through this forecast period. Temperatures will warm to slightly warmer than normal for mid-December. Thursday, the previously mentioned weather system will move off to the east sending a cold front into the Panhandles around mid-day, but not before temperatures warm into the upper-50s to low-60s.
We will see cooler conditions in the wake of a front today. Breezy NNW winds will prevail early this morning and will gradually weaken and become light and variable as a high pressure center drops south across the FA. This high should then shift off to the southeast by tonight, with light southerly winds on the backside of the departing high by dusk. Lee troughing will resume tonight into Thursday morning. Moderating conditions are expected Thursday with highs a bit warmer. High pressure will eventually shift south through the day with winds becoming light and variable. Weak southerly winds expected by tonight as the high pressure center shifts off to SE.
(Today and tonight) Winds behind the cold front that moved through this morning will be breezy across the whole area. Winds will shift to the south late tonight, but the cooler air will stick around long enough to help the lows get down into the upper 20s to low 30s.
1257 AM EST Wed Dec 18 2024 High pressure will weaken this evening, and the next weather system will bring rain across the Ohio Valley on Wednesday.
A weak warm front will move over the area tonight, generally bringing light rain to the valleys below 4000ft, and light snow to the mountains. Then a ridge will build into the region bringing a temperature inversion aloft with low clouds and fog trapped in the valleys for the next several days. Temperature forecast confidence is low at this time depending on where the low clouds and fog set up over the area. An upper level ridge will build over the area on Wednesday night and will continue through Thursday and into the beginning portion of the upcoming weekend. The upper level ridge will bring dry weather but will also cause a strong temperature inversion to form in valley locations.
431 AM MST Wed Dec 18 2024 - Some lingering travel impacts with slick roads and reduced visibility in the high mountains. Flat upper ridging is expected to build across the region today, leading to warmer and drier conditions for the forecast area.
524 AM CST Wed Dec 18 2024 (Today through Thursday) Key Messages: - Dense Fog Advisory in effect through 9AM this morning - Strong Cold Front pushes through the region today With winds calming overnight across South Texas, fog has already began developing over the inland portions of the Coastal Plains into Brush Country. This is expected to burn off around mid morning ahead of the arrival of the cold front. With the presence of above normal moisture in the region, expect rain chances to be generally low with the highest potential being along the front (30-45%).
A cold front is expected to move through the region during this afternoon and into this evening. Once the cold front moves through, the dry air behind it will put an end to the possibility of rain for the rest of the short term forecast. As for the temperatures, the highs for today are expected to be in mostly in the 80s today. However, the low temperatures for tonight will be much colder with lows expected to be in the 50s for most of the area, and parts of the Northern Ranchlands could even get into the upper 40s.

A cold front is passing over the Cascades at this time and will sweep across the forecast area this morning before exiting to the east in the afternoon. A ridge of high pressure will move over the region Wednesday night through Thursday. This will lead to some shallow inversions Wednesday night and some patchy fog development around the Lower Columbia Basin.
The upper-level pattern shows a ridge over the Intermountain West and a trough moving through the Central Plains associated with the system that brought precipitation to South Dakota yesterday. Today will be cooler as winds have shifted to the northwest which has brought cooler temperatures to the area. We'll see the ridge to our west move across the area today leading to a wind shift to southerly by this afternoon. The system currently off the coast of Washington and Oregon will move across the Rockies bringing a strong cold front through the Northern Plains on Thursday.

A cold front will pass through the area tonight leading to light northwesterly winds as IFR ceilings move in from the northwest behind the front after midnight. The main talk today will be the cold front that will push through the area this afternoon and evening. A rather deep trough will progress across the area today. Ahead of the trough, deep southwesterly flow will allow for increasing clouds and moisture. As the trough moves across the area by late this afternoon and into the overnight hours, it will drag a cold front across the area. Behind the front, cooler and drier air will move in on Thursday.
Otherwise, a quiescent week is ahead with ridging and above normal temperatures expected through the start of the weekend.

The weather forecast over the next several days more resembles what we would expect in November as high temperatures across the lower deserts will flirt with the 80 degree mark, or even likely just surpass it within the Phoenix metro. An unseasonably strong high pressure system is currently building across our region from the southwest and it will dominate our weather conditions through the coming weekend. Today will bring sunny skies and much warmer conditions, especially across south-central Arizona where highs will likely top out at or just above 80 degrees.
- Blustery on Thursday behind cold frontal passage with wind gusts to 35-45 mph mainly west of I-35. Roads will still likely be slick in spots for morning commute in central and northern Iowa due to sub-freezing overnight air & sfc temps combined with yesterday's wintry precip. Have trended winds towards the 75-90 percentile of the NBM to capture the higher wind potential. Temperatures will be a bit warmer for Thursday, though gusty winds will mitigate the "warmth".

Moderating conditions are expected Thursday with highs a bit warmer.
- Cold front pushes through the area this afternoon making things noticeably colder.
A few island communities in the Lower and Middle Keys have received less than a tenth of an inch of rainfall totals, otherwise the remainder of the Keys have remained dry. The KKEY 12Z sounding revealed that moisture is still present in the lower levels and MIMIC PWAT confirms this, therefore, isolated showers will continue through the afternoon into tonight. As a high pressure slides further east into the Atlantic, breezes will continue to slacken across our CWA. From synopsis, high pressure over the North Atlantic will continue sliding farther east loosening its grip across the Florida Keys.
Updated at 1041 AM CST Wed Dec 18 2024 - Colder today behind cold front with gusty northerly winds.
Cold front passage tonight will send drier air and cooler temperatures for Thursday. Peak gusts only recorded in the low to mid 30's mph, especially at CHA, TYS, and southwest VA.
