The National Weather Service has issued a Severe Thunderstorm Watch that includes most of the Arklatex until 6pm. Storms will begin to develop along and ahead of a strong cold front by mid afternoon. Damaging wind will be the biggest threat with these storms. We could also have a few isolated reports of large hail and a tornado or two.
Our severe storm outlook today from the Storm Prediction Center remains relatively unchanged.
All counties and parishes along and south of Interstate-30 are in the ‘slight risk’ zone for strong/severe storms, meaning scattered severe weather reports are possible, including isolated intense storms. A ‘marginal risk’ encompasses areas north of I-30 through Oklahoma and Arkansas.
The primary threat with thunderstorms that form ahead and along a cold front this afternoon and evening will be for high wind, and large hail (quarter sized or larger). An isolated tornado or two will be possible, particularly across east Texas and northwest Louisiana during the afternoon. We will transition to more of a wind threat as a squall line forms during the evening.
Remember the worst places to be during severe weather are in a vehicle or a mobile home. Make plans to move to sturdy shelter if a warning is issued for your location.
Warm, unstable air is in place this morning as temperatures are in the 60s and low 70s. A breezy south wind is pumping Gulf moisture into the region resulting in a few lightly scattered showers that will continue this morning under otherwise mostly cloudy skies. Highs ahead of the approaching front will be in the 70s and low 80s.
Brief heavy rainfall will be possible under any thunderstorms, and likely rainfall amounts will range from .25 inches across the northern ArkLaTex, to 1.5 inches in some areas south of I-20.
The severe weather threat will end as storms move southeast tonight. Much cooler air will filter in behind the front overnight dropping lows into the 30s and 40s by sunrise on Wednesday.
