Cold Front Pushing Through Valley

RIO GRANDE VALLEY:

Here are today’s high and low temperatures around the Valley:

Brownsville- 75/49
Harlingen- 75/44
McAllen- 77/47

A very warm day in the Valley today.  Afternoon highs were a bit higher than yesterday’s forecast because the front approaching the RGV is moving more slowly than expected.  Now, showers are beginning to develop along the front and located on Starr and Hidalgo County line.  Tonight, expect mostly cloudy skies with lows in the lower 50s in the upper Valley and upper 50s in the lower Valley.  There is a 30% chance of showers and light rain tonight as the front passes.  Light to moderate showers are falling near the coast, currently.  Here is a look at the current (8:00 pm CST) RADAR and front position (from HPC):

Current RADAR and front position at 8:00 pm CST 1/23/2011

(1/24/2011): The cold front will pass through the Valley tonight and will stall near the coast, where a surface low will develop along the frontal boundary, early tomorrow morning.  This low will increase shower chances (30%), especially near the coast, in the morning.  Skies will be mostly cloudy throughout the day.  Afternoon highs will be in the lower-to-mid 60s.  Winds will be out of the northwest at 10-15 mph.  Monday night, skies will begin to clear after midnight, with lows in the mid-to-upper 40s in most areas of the Valley.  Winds will remain out of the north and northwest, but calmer at 5-10 mph.

(1/25/2011): Expect sunny skies on Tuesday.  Highs will be in the mid-to-upper 60s.  Winds will be gusty out of the north and northwest at 15-20 mph, with gusts up to 25 mph.  Tuesday night will be mostly clear with lows in the mid-to-lower 40s; winds will be out of the north at 8-13 mph.

(1/26/2011): Wednesday looks to be a beautiful day.  Sunny skies will allow high temperatures to be in the upper 60s/lower 70s.  Winds will be out of the north-northeast at 5-10 mph.  Wednesday night will be partly cloudy with with lows in the mid 40s.

Edinburg 3-day Forecast:

(1/24/2011): 63/50…Cloudy…30% chance of showers…Winds NW at 10-15 mph
(1/25/2011): 66/47….Sunny….Winds NNE at 15-20 mph G26 mph
(1/26/2011): 70/42….Sunny…Winds NNE at 5-10 mph

REST OF THE NATION:

…Great Lakes….

An area of low pressure in Canada will be crossing the border, into the US at the MN/ND border that will bring snow to the area and for the Great Lakes region.  No major snowfall is expected from this.

…South and Northeast…

A surface low that will develop along the S. TX coast will be pushing through the Gulf of Mexico and into the Atlantic, where it will then push towards the northeast states by Thursday and Friday of this week. The big question is: how close to the coast will this low be?  If it’s too far off shore, then only the extreme coastal area in the northeast will be affected, if that.  If it’s closer to the coast, then the Northeast will get pounded again with snow.  One thing is for sure: FL, GA, SC, NC and VA will all be affected with rain and snow as this low passes them.  The rain/snow line will most likely be around VA.  More on this to come..

Northwest…

The Northwest is in store for more rain and snow, as another storm system from the Pacific is forecast to move inland tonight.  A shortwave trough is set to move in tomorrow night, bringing heavier rain for the coast of WA and heavy snow inland for ID and MT.
