A Soggy South


The much needed rain has passed and drier conditions will be in store for the Valley this week.  I, myself, recorded 1.14″ of rain that fell Saturday, alone.  Below, is a RADAR estimation of rain that fell on Saturday in the Rio Grande Valley.

Today, temperatures were not as chilly as the previous days due to westerly and southerly winds.  Both Brownsville and Harlingen recorded highs of 68 degrees, while McAllen recorded a high of 69 degrees.  Tonight will be mostly clear with lows in the mid-to-upper 40s.  A saturated ground, calm winds and radiational cooling all allow for dense fog to develop later tonight and into early tomorrow morning.  Please use low beams if driving.

M.L.K Day (1/17): Patchy fog will still be in the area during the early morning hours Monday, mostly sunny by the afternoon.  Highs will be in the lower-to-mid 70s with winds out of the south southeast at 5-10 mph.  Monday night will be mostly clear with lows in the upper 50s in most areas.  Fog will return after midnight and into Tuesday morning.

(1/18): A weak cold front will pass through the Valley Tuesday morning, shifting winds out of the north northwest at 10-15 mph, with gusts at 20 mph.  Skies will be mainly sunny.  Afternoon highs will still be warm, reaching the upper 70s and possibly lower 80s in the upper Valley.  Tuesday evening, lows will be a bit chilly, in the lower 50s under mostly clear skies.

(1/19): Wednesday will be a bit cooler.  Mostly sunny skies with highs in the lower-to-mid 70s.  Winds will be out of the north northeast at 10-15 mph, with higher gusts.  Wednesday night will be partly cloudy with lows in the mid-to-upper 50s.

Edinburg Forecast:

(1/17): 76/49…mostly sunny…winds SSE at 5-10 mph

(1/18): 82/56…mostly sunny…winds NNW at 10-15 mph G20 mph

(1/19): 74/55…mostly sunny…winds NNE at 10-15 mph G20 mph


The upper-level trough that was partly responsible for the rain in the RGV on Saturday is now over E. TX and LA.  It looks as if rain is slowly starting to diminish, somewhat.  There is a counter-clockwise spin on RADAR, which indicates low pressure.  This upper-level trough will continue affecting the South with rain, and will begin to start lifting over FL early Tuesday, bringing them some much needed rain.

Numerous flood advisories, watches and warnings continue to be issued out in the Pacific Northwest from moisture flow from the Pacific Ocean and mountain runoff.  A surface low in the Gulf of Alaska plus a surface high off the coast of CA is allowing this moisture to continue to flow into WA and OR.  And, since it’s been raining and snowing constantly in the Northwest, recently, runoff from the mountains have caused major flood issues for OR, ID, and WA.

A surface low is beginning to develop over the ND/SD border that will push south and eastward.  The surface low, aided by a shortwave trough in the mid-layers of the atmosphere, will bring snow for North-central, Midwest, and Ohio Valley regions for the next 3 or 4 days.
