I sincerely apologize for taking a break from my blog, as I was out of town and away from the internet. Daily blogs from me will continue until further notice.
Rio Grande Valley:
Since my last blog, weather has continued happening (duh), as weather will do. For the Rio Grande Valley, there was a noticeable change in weather Saturday evening into Sunday. There was a threat for severe weather as a couple of disturbances occurred at once over South Texas, in order for strong thunderstorms to form. An upper level shortwave trough, along with Gulf moisture flow and a cold front sparked rain and thunderstorms late Saturday night and early Sunday morning. As a result of these ingredients, a nice squall line (line of thunderstorms) formed from northeast Texas, stretching down to the RGV. Cyclogenesis (formation of a low) occurred at the surface and pushed through mid-Texas Sunday morning and is responsible for the snow/sleet/freezing rain over the southeast right now.
Although most of the RGV missed out on the rain and thunderstorms, the fact that the RGV was in a potential threat for severe weather was an eye opener, as severe weather occurs only a few times a year. The forecast for the next 3 days for the Rio Grande Valley will be a chilly one as an arctic cold front is set to move through tonight into early tomorrow morning.
(1/11): Tuesday will start off with gusty winds out of the north at 15-20 mph, due to the cold front passage. A slight chance (20%) of rain/drizzle is in the forecast because of the frontal boundary, but otherwise, expect mostly cloudy skies with highs in the low 50s and dropping throughout the day. During the evening, expect lows to be in the mid 30s! Bundle up!
(1/12): Wednesday’s highs looks to be even colder than Tuesday’s! Expect high temperatures to be in the mid-to-upper 40s under mostly cloudy skies, with a slight chance (20%) of showers/drizzle. Winds will remain out of the north at 10-15 mph. Wednesday night, expect mostly cloudy skies with a slight chance of showers, lows in the upper 30s. Stay warm!
(1/13): Much of the same for Thursday. Cold, with highs in the upper 40s/lower 50s. Winds will be out of the northwest at 10 mph. The chance of showers/drizzle is still in the forecast for Thursday (20%). Thursday night, expect mostly cloudy skies with lows in the mid-to-upper 40s with northwest winds.
Rest of the Nation:
Two major winter storms are currently making an impact on the nation at this time. One surface low is currently over the Midwest region, making its way toward the Ohio Valley tomorrow. This low has brought lots of snow for the mid-section of the United States and will continue bringing heavy snow for the Ohio Valley.
The other surface low is currently south of the Florida Panhandle, but is making a huge impact on the Carolinas and Georgia due to warm, moist, Gulf air interacting with cold air behind a front. Areas of Alabama and Georgia, and other parts of the Southeast, received freezing rain and drizzle from this interaction. Freezing rain is one of the most dangerous precipitation types as it can do so much damage to agricultural and electrical units.
The BIG problem, in the long run, over the next 2 to 3 days is going to be in the Northeast. The two low pressure systems are forecasted to merge together over the northeast and bring blizzard conditions for the Northeast in the next 48-72 hours. More on this to come.
