A surge of arctic air will bring a variety of cold weather impacts to the area from today through Wednesday night/Thursday morning. Please see below for details by day.
...Today...
Northerly wind will increase to 20-25 mph sustained with frequent gusts to around 35 mph from about 12 Noon through around Midnight tonight. A few peak wind gusts of 35-40 mph are also possible at times mainly during the afternoon hours today.
Present indications suggest the wind will decrease mainly into the 15-25 mph range with occasional gusts to 30 mph around or shortly after Midnight tonight.
The strong, gusty winds combined with slowly falling temperatures (mainly in the 40s) will result in wind chill values in the 30s this afternoon, and the upper 20s by this evening.
...Tuesday...
Wind Chill values will be in the 20s throughout the pre-dawn and much of the morning hours on Tuesday - including the morning rush/transportation period. During this time, minimum Wind Chill values are likely to reach the lower 20s especially from near 4am through about 8am on Tuesday morning.
Anyone who must be outdoors for extended time periods (i.e., working outdoors, waiting for a bus, etc.), should take precautions such as wearing loose fitting, layered clothing under a coat for additional insulation. Also be sure to cover the ears and wear gloves to minimize exposure to the cold wind chill temperatures if you will be outside for more than a few minutes during this time period.
Wind Chill values will moderate into the 30s by around 12 Noon on Tuesday, and will continue at those levels into the afternoon before dropping back into the 20s on Tuesday evening.
Early on Tuesday morning, temperatures will fall to around 33-34 degrees across most of the area. A few spots West of I-35 could briefly touch the freezing mark near dawn on Tuesday. Further West of the metro, a hard freeze is likely across the Hill Country.
...Wednesday...
Temperatures are expected to be at or below freezing from late Tuesday evening/Tuesday night through about 8am on Wednesday morning. Minimum temperatures will likely reach the 28-30 degree range from around 4am through about 6am or so on Wednesday morning.
With temperatures forecast to be at or below freezing for approximately 10 hours, this will result in the first hard, killing freeze of the season across the area. Readings will quickly moderate during the daytime hours, reaching the lower 50s by Wednesday afternoon.
Wind Chill values will be in the 20s once again for the morning rush period on Wednesday.
...Thursday Morning...
Temperatures will fall to around freezing or just below near dawn on Thursday, with wind chill values in the 20s for the morning commute.
