Severe storms and flash flooding likely today —
SEVERE T-STORM WATCH is in effect for northern Arkansas counties through 9 AM. A line of storms capable of 70 mph winds, ping pong ball size hail, and isolated tornadoes is moving through.
FLASH FLOOD WATCH is in effect through 7 AM Thursday along/ southeast of I-44 where another 1-3″+ is likely, rain totals up to 5″+ possible. This would cause flash floods. Rivers, creeks are most susceptible to flooding.
A round of storms moving through Arkansas this morning is bringing heavy rain and lightning. Missouri has been dry overnight because of a cap in the atmosphere — all of the ingredients for storms are there but bottled up. This cap on the energy is weakening, and fuel for storms is growing.
As the front approaches from the west, waves of storms will ride areas along/ south of the front — which happens to be in line with I-44. Storms will be likely southeast of the interstate today, coming in rounds with little breaks in between.
There will be ample instability, or fuel for storms from a warm, humid air mass, in place. The wind energy is there, but not as impressive. This will lead to a severe threat that includes 70 mph damaging winds, golf ball size hail, and isolated tornadoes. Frequent lightning and heavy rain will also be threats. Flash flooding will likely be the most widespread concern.
Timing for severe storms is after 12 PM through the evening hours, wrapping up by 7-9 PM. The tornado threat will be a much smaller window, from about 3 PM to 7 PM.
Storms work to exit east overnight. Temperatures drop from highs around 80 degrees to lows around 60 degrees.
Tomorrow will finally be quiet! A few storms could linger in the morning, but rain clears and skies should be partly to mostly sunny. Highs will be cooler in the middle 70’s.
Warm, seasonal sunshine returns on Friday with highs in the 80’s.
Spotty storms are possible through the weekend. No day will be a washout and the severe threat looks limited. Highs stay warm in the lower 80’s.
