RIO GRANDE VALLEY:
The cold front pushed through the Valley around 4 pm CST, bringing cloud cover and strong northerly winds. Parts of the RGV had wind gusts over 40 mph! Wilacy and Cameron Counties saw most of the rain, although it was very light and brief. Today’s high temperatures were: 78 degrees in Brownsville, 77 in Harlingen, and 75 in McAllen. For tonight, expect temperatures to be in the mid-to-upper 30s in most areas of the Valley. Clouds will begin to clear after 8 pm tonight, resulting in radiational cooling. Winds will die down a bit, but still be pretty breezy out of the north at 10-15 mph.
(1/21/2011): Tomorrow, highs will be in the mid-50s under clear skies; high pressure will dominate the area. Winds will start out from the north, then turn out of the east after noon and will be between 5-10 mph. Winds will make it seem a bit colder, so prepare if outdoors. Tomorrow night will be clear and cold. Lows will be in the mid-to-upper 30s, with winds out of the northeast at 5-10 mph.
(1/22/2011): Saturday will be sunny, with highs warming up to the mid-to-upper 60s. Winds will be shifting from north to southeast at 6-11 mph. Saturday night, expect lows to be in the upper-40s/lower 50s from the warmer, southeasterly winds. A streamer shower or two is possible near the coast, from the onshore flow from the Gulf.
(1/23/2011): High temperatures will return back to normal for Sunday. Highs will be in the lower-to-mid 70s under mostly sunny skies. Winds will start out of the southeast in the morning, but will turn out of the north due to another cold front that will arrive Sunday evening. This front will increase clouds and increase rain/drizzle chances (20%). Sunday night will be partly to mostly cloudy with lows in the mid-40s.

REST OF THE NATION:
The surface low that pushed through MO and brought snow and wintry precipitation for the Midwest intensified over KY this morning and is propagating northeast. This is the same low that is associated with the cold front that passed through the RGV today. The National Weather Service has issued winter storm warnings and advisories for much of the northeast as this surface low will proceed towards the northeastern states. Heavy snowfall will occur for this region, especially for states such as CT, RI, MA, south N.H. and along the ME coast, over the next day and a half.
Northwest flow aloft and a surface warm front are causing snow to develop over MT. Blizzard warnings have been issued for portions of south-central MT. Winds are blowing at 30 to 40 mph, behind the front, with gusts of 55 mph!
