Severe Weather On The Horizon:

We saw the first severe weather outbreak of the season last week, when thunderstorms marched across portions of Arkansas, Oklahoma and Missouri. They produced damaging winds, golf ball size hail stones, and several tornadoes which impacted such areas as Moore, OK and Sand Springs, OK.

Well after a quiet stretch of weather over the weekend, we are seeing signs of the next round of severe weather to come on through. For Tuesday, we can be expecting to see storms fire up in the midday hours. Temps will be getting into the 80s and possibly even to 90° and the moisture will be surging northward from the Gulf of Mexico. If the high-level cloud cover remains thin, we can get that sufficient heating needed to get those storms really going. For the storms that do form, we can expect to deal with large and damaging hail; likely 1-2″ in diameter. Isolated tornadoes can’t be out of the question, especially in the SLIGHT RISK zone, which includes cities such as Wichita Falls, TX and Lawton, OK.

spc day 3For Wednesday, a lowered severe threat will linger across the Southern Plains, while the more substantial severe threat will be further northward; over portions of the Central and Northern Plains. The SLIGHT risk zone for severe weather will cover more territory on Wednesday than Tuesday, with roughly 96,000 square miles in that zone. Major cities such Omaha, Des Moines, Topeka and Grand Island. Warm, moist air is going to be sent further northward over the course of Tuesday afternoon and into Wednesday. Daytime high temps on Wednesday, across the Midwest, will range from the 60s to the 80s, possibly even into the low 90s across portions of western Texas. Scattered thunderstorms will be popping up in the midday hours along the cold front and move eastward through the afternoon and evening hours. Large and damaging hail, along with powerful wind gusts will be the main threats with Wednesday’s severe weather. Isolated tornadoes are possible with some of the thunderstorms moving through the area. In the evening hours, an MCS (Mesoscale Convection System consisting of a complex of thunderstorms ) may form towards the Lower Ohio River Valley. A system like that brings about heavy downpours, frequent lightning and gusty winds. It is usually circular or oval in shape, and lasts for several hours through the evening, and sometimes through the overnight.

Stay tuned for more details.
