Old Man Winter's glancing blow brings frigid temperatures to RGV

"Old Man Winter" is bringing another round of cold, arctic air to the Rio Grande Valley.

It's all part of the cold air mass that is gripping the nation's heartland.

The front that moved in Sunday ushered in strong north winds and the coldest air this season so far into deep South Texas.

Temperatures today are expected to stay in the 40's today and drop to the 30's this evening with overcast skies. The National Weather Service has already issued several warnings, watches, and advisories.

Today, a Wind Chill Advisory will remain in effect until 10 a.m.

The combination of temperatures in the 40's and wind out of the north at 15-20 mph, gusting to 25, will make it feel like it is in the 30's.

On Tuesday, a Freeze Warning has already been issued for out northernmost counties, including Zapata, Jim Hogg, and Brooks from 12 Midnight through 8 a.m.

Temperatures are expected to drop to 32 degrees or below for at least 2 hours in these counties.

On Tuesday, a Freeze Watch remains in effect in Starr, Hidalgo, and Kennedy counties for the same time frame. Temperatures may dip to 32 degrees or below for a short period of time.

It is important to remember the 3 P's: plants, pets, and pipes.

Some plants that are not used to this climate may be affected and it is best to make preparations to protect them from the elements.

Pets should be brought inside or given sufficient warmth.

Pipes, especially those that are exposed, are susceptible in extreme cold temperatures.

Additionally, a very slight chance ({<}20%) for light freezing precipitation, mainly flurries, exists after midnight until the dawn hours primarily in the western counties.
