Rio Grande Valley:
It finally feels more like winter in the Rio Grande Valley. A cold day under overcast skies really made it feel like getting underneath a warm blanket and just let the day pass by. Temperatures stayed in the lower 40s in the western Valley. McAllen hit 45 as a high today; 49 was the afternoon high in Harlingen; Brownsville was the warm spot reaching 58 today. Tonight, will be another chilly one, but staying above freezing because of the cloud cover. I expect tonight’s lows to be in the mid-30s in Starr County, lower-to-mid 40s in Hidalgo County, and lower 50s near the coast. Winds will remain out of the north and northeast at 5-10 mph.
(1/13): On Thursday, high temperatures will flirt with the 50 degree mark in the mid and lower Valley, upper 40s in the upper Valley. Skies will be cloudy with a chance of light drizzle and rain throughout the day. Winds will be out of the north and northeast again at 10 mph. Thursday night will be mostly cloudy with a slight chance of light showers with lows in the lower-to-upper 40s.
(1/14): For Friday, the arctic high pressure centered in KS will continue moving east, and as this occurs, this will shift our winds out of the southeast and bring in warmer weather. Skies will remain cloudy due to upper-level moisture and lower level moisture from the Gulf of Mexico. In fact, a greater shot (30%) of precipitation is expected for Friday afternoon. Afternoon highs will be in the lower-to-mid 60s. Friday night looks to be cloudy, with a 40% chance of showers. Lows will be in the lower 50s.
(1/15): A shortwave trough at 500mb is expected to bring in moisture advection on Saturday. Thus, an increase of showers and even thunderstorms is expected, especially during the evening hours. Afternoon highs will be in the upper 60s/lower 70s in most areas in the RGV. Winds will be out of the southeast at 10-15 mph. Increased chance (60%) for storms on Saturday night, as the shortwave trough moves over the area. Lows will be in the lower 60s/upper 50s.
Forecast for Edinburg, TX:
(1/13): 49/41…winds out of the northeast at 10 mph…20% chance of drizzle
(1/14): 62/44…winds out of the southeast at 10-15 mph…30% chance of light rain (day), 40% chance of rain (night)
(1/15): 68/55..winds out of the southeast at 5-10 mph….50% chance of rain/storms (day), 60% chance of rain/storms (night)
Rest of the Nation:
High pressure at the surface dominates much of the Central United States, which is keeping things quiet weather wise. An upper-level shortwave trough, visible at 500mb, is moving over the Pacific Northwest, and is associated with a surface low that is bringing rain near the coast of WA and OR and snow in the higher elevations. This disturbance is expected to continue moving east into ID and MT, bringing them snow. Models continue bringing in moisture from the Pacific into WA, OR, and northern CA over the next few days, that might bring flood issues to the areas who have previously received rain and winter storm warnings to areas who have seen snow.
The two surface lows that merged into one single low is now just south of ME and continues to move north and east, dumping inches and even feet of snow in areas. This system should be out of the CONUS in the next 30-36 hours, but not before it continues bringing havoc to the Northeast.
