Severe Thunderstorm Threats and Areas of Heavy Rain This Week

A weather system producing areas of heavy rain will slowly move northeast along the east coast into mid-week. Meanwhile, a new weather system may produce severe thunderstorms potentially containing large hail, damaging winds, and isolated tornadoes in the Plains and Mississippi Valley. Heavy rain and flash flooding may also develop Wednesday for the Mississippi Valley and Upper Great Lakes. Read More >

It'll be a very warm day with gusty south winds 20 to 30 mph across the eastern half of the area where a Wind Advisory will be in effect from 10 a.m. CDT through midnight CDT tonight. In addition to the gusty winds, highs will warm to between 90 and 95 degrees west of I-35/35W, to between 85 and 90 degrees further east. With the windy conditions, remember to secure lightweight outdoor items such as patio furniture and trash cans. In addition, high-profile vehicles traveling on east-west oriented highways/interstates, as well as boaters on open waters should use extreme caution this afternoon and evening.
A very warm and breezy to windy day today, as a surface dryline moves into Western North and Central Texas by this afternoon. An elevated fire danger will exist behind the dryline where southwest winds 15 to 20 mph will combine with hot temperatures in the lower to mid 90s and low humidity values. Outdoor burning is highly discouraged across this area. Please refrain from tossing cigarette butts out of moving vehicles as well, as they can ignite grass fires. It will be windy and more humid further east.
A fast moving cold front will sweep across the region on Wednesday and bring a chance of showers and thunderstorms. The best window of time for storms will be between 10 AM and 3 PM. Some severe storms will be possible, especially near and east of the Interstate 35 corridor. Large hail and damaging winds will be the primary hazards, however, an isolated tornado can't be ruled out.
Friday will be a very complex day with regard to storm chances across northern and western North Texas. A strong cap will be in place over much of the area, but slightly weaker along and north of a warm front near the Red River Valley. Should isolated storms breach the cap aloft, they will likely become strong to severe quickly with large hail and damaging winds being the main hazards. The tornado threat appears LOW, though areas along and north of the warm front would be susceptible to a tornado or two.
A deep upper level trough, a dryline and a cold front will bring thunderstorm chances to North and Central Texas this weekend. Some storms could be severe, with the most likely timing being late Friday into Saturday. However, it is still a bit too soon to try to narrow down the specifics regarding timing and primary severe threats. We will know more as the system gets closer and better guidance is received.
