RIO GRANDE VALLEY:
Here are today’s high/low temperatures:
Clouds quickly cleared after the morning hours, although parts of the Valley received light rain/mist. Tonight will be partly cloudy with lows in the lower 50s/upper 40s. Winds will be light out of the north-northeast.
(1/25/2011): Tomorrow will be sunny and breezy, with afternoon highs in the mid-to-upper 60s, due to cold air advection (CAA). Winds will be strong out of the north at 15-20 mph with higher gusts. It wouldn’t surprise me if the NWS issued some sort of wind advisory tomorrow. But in any case, please be aware of fires that can spark up because of dry, windy conditions. Tomorrow night will be mostly clear and chilly, with lows in upper 30s/lower 40s. Winds will begin to shift out of the east late Tuesday night.
(1/26/2011): High pressure will still be dominating on Wednesday, under sunny skies, with highs in the upper 60s/lower 70s. Winds will generally be out of the east between 8-13 mph. Wednesday night will be mostly clear. Lows will be dipping into the mid 40s, with winds out of the east-northeast at 6-11 mph.
(1/27/2011): Much of the same for Thursday. High pressure will still be in the area, which, in turn, will cause mostly sunny skies. Highs will be in the upper 60/lower 70s with winds out of the north at 6-11 mph. Thursday night will be partly cloudy with lows in the mid 40s again.

REST OF THE NATION:
An area of low pressure that developed over the S. TX coastline is now causing a lot of rain falling in LA, MS, and extreme southern AR. The low is located just south of the TX/LA border and will be progressing inland towards the New Orleans area. This will continue moving towards the Atlantic coast and then ride up the east coast, dumping lots of rain (and eventually snow) in its path. I do expect this low to be better organized once it does make it to the east coast. Here is a snap shot of the low:
Freezing rain, sleet, and snow that is falling over the Pacific Northwest is caused by an upper-level shortwave trough and Pacific moisture. Divergence is evident at 300mb over central and eastern WA as well as northwest MT. As the shortwave begins to move east and south, so will the precipitation chances. Except for some freezing rain issues in western MT, no big threats are expected out of this storm.
…Eastern Great Lakes…
A weak upper-level trough is bringing snow and wintry precipitation for parts of the eastern Great Lakes region.
