Brownsville reached a high of 72, while Harlingen and McAllen reached 68 and 69, respectively. Tonight will be foggy, but not as dense as last night. Skies will be partly cloudy to mostly cloudy with lows in the mid-to-upper 50s.

REST OF THE NATION:
A mid-level trough is bringing precipitation for the Mid-West. Central MI is currently getting some heavy snowfall. This trough will be moving east and dumping snow for the Ohio Valley, as well as the Northeastern states.
The East coast is getting drenched from a combination of a surface low that developed over the Gulf of Mexico and is now riding along the coast, and a jet streak aloft, causing divergence along the coast. Persistent rain will likely cause flooding issues in the Carolinas and VA. Because this low is going to strengthen and relocate northward, winter storm watches and warnings, as well as a gale warning off the northeast coast, have been issued for the Atlantic Northeast. This means more snow for an area that has been impacted by winter weather all winter.
More flooding problems continue for the Northwest. Another swath of precipitation is forecast to fall tomorrow afternoon.
