Severe weather outlook for Wednesday from Houston-Galveston NWS

Severe weather outlook for Wednesday from Houston-Galveston NWS

National Weather Service

Although northern and western parts of Galveston County have received up to 1 ½ inches of rain over the past 14 days, precipitation has been scarce during that period closer to the coast. The NWS office in League City/Dickinson has measured only 0.03 inch of rain since March 14 and, in Galveston, the official reporting station at Scholes Field has seen but a trace.

Those of us near the Gulf, already are beginning to note some effects of the dry spell on our more vulnerable plants and are definitely looking for some relief.

Fortunately, two upper-level systems expected to move from west to east into Texas and the Plains over the coming seven days may be just what the doctor ordered. A level of stable air aloft (called a cap) has more or less squelched rain chances near the coast over the past two weeks. There is some hope, however, that the next two systems may produce enough instability to “break the cap” and allow thunderstorm activity near the coast. In fact, both systems may produce severe weather and heavy rain, though the bulk of that activity is again expected to be off to the north of Galveston County.

At any rate, our first chance for will come tomorrow into early Wednesday, as the upper-level system moves in along with a weak cold front. The second should impact our area from sometime Sunday into Monday.

On a side note, the timing on these systems should allow for fairly good spring weather on Friday and Saturday….for those of you planning outdoor activities this weekend.
