RIO GRANDE VALLEY:
Here are today’s high and low temperatures:
High pressure is ruling over south TX, which left fair skies for today. Winds were very breezy today due to this high pressure. Tonight will be mostly clear, allowing for radiational cooling to take place. Lows will be in the upper 30s/lower 40s. The extreme northern Valley could see temperatures in the lower-to-mid 30s. Winds will be out of the north at 0-5 mph.
(1/26/2011): High pressure, located in north-central TX will begin moving east, shifting our winds in the RGV out of the east at 10-15 mph for tomorrow. Skies will be sunny with highs in the lower 70s for much of the Valley. Tomorrow night will be partly cloudy with winds out of the northeast at 5-10 mph.
(1/27/2011): As a ridge of high pressure pushes east into the Gulf of Mexico, it will switch our winds from the northeast to the east on Thursday. This will also increase lower-level moisture and increase cloud cover for both Thursday and Friday. Afternoon highs will therefore be lower, in the mid-to-upper 60s, due to cloud cover. Lows for Thursday night will be in the lower-to-mid 40s. Skies will remain mostly cloudy, with winds becoming southeast at 5-10 mph .
(1/28/2011): Friday will start off chilly (mid-to-upper 40s), then warm up in the lower 70s, under mostly cloudy skies. Winds will be out of the east at 5-10 mph. Friday night will be milder, with lows in the mid 50s, under cloudy skies.

REST OF THE NATION:
Much of the South and Southeast are in a drought of some sort (see figure 1 below). A surface low continues to saturate much of the Southeast and bringing severe storms for central FL. The amount of rain falling will absolutely help with the drought conditions for the South. Gulf flow from this low is even causing snow to fall over western TN and KY and will wet bulb the temperatures in the TN Valley and along the Appalachian Mtns tonight, causing the rain to turn into snow. Winter storm warnings and advisories have been issued by the National Weather Service (see figure 2). Some areas in the warnings may see half of foot of snow, with isolated areas to see a foot of snow. This storm system is forecast to ride along the east coast in the next 24 to 36 hours. It will then make a northeast turn, avoiding direct hit with the Northeast, but will still drop lots of snow and have gusty winds for states and parts of states along the Atlantic.
