Rio Grande Valley:
Dry, gusty winds were the major impact today for much of the Rio Grande Valley. The entire Valley, including Jim Hogg, Brooks, and Kenedy Counties, was under a Red Flag Warning for most of the day. Tonight, clear skies, with gusty winds at times from the south and southeast but should calm down a bit as the night progresses. Lows in the upper 50s.
For tomorrow, expect sunny skies and warm temperatures ranging from the upper 70s in the lower Valley to low-to-mid 80s in the upper Valley. Winds will be calmer ranging between 10 and 15 miles per hour from the south and southeast.
Friday, a cold front, associated with an area of low pressure in the mid-section of the United States, is expected to move through the RGV early in the morning. With this cold front, comes wind shifts out the north and also will develop clouds that increases the chance of rain slightly for Friday morning. Temperatures will also drop for afternoon highs. Expect the highs in the mid-to-upper 60s.
Rest of the Nation:
A large band of snow extends from North Dakota to the Tennessee Valley. Numerous winter storm advisories and winter storm warnings have been issued for at least 15 states in the path of an area of low pressure that will be moving across Tennessee and into North Carolina/Virginia. Ice and snow will be the main threat for these regions. The low pressure will move out of the states by late Thursday night and early Friday morning.
Heavy lake effect snow is continuing to fall in upper state New York and portions of northwest Pennsylvania and is expected to continue to fall throughout most of the day tomorrow. Some remote areas are expecting up to 2 feet of snow.
