Better late than never? Honestly wasn’t really expecting this to occur either but looks like we have a chance for some severe storms to form through the overnight hours into 7am. This is mainly for large hail and severe winds. Tornadoes are not expected to be an issue through overnight. Looks like ill be awake most of the night again!

BAH! Sorry about the misinformation yet again. Basically the same situation occurred today, as did on Friday. A strong temperature inversion or cap held in place all day and basically prevented all but 1 storm from developing. The forecast was for the morning overcast clouds to burn off with daytime heating and open the way for unstable air to kick in full speed and spawn some large storms. Instead, the clouds didnt burn off, so the unstable air didnt develop and the cap held. One storm formed about 95 miles to our west but it will not affect us.

Sorry for that everyone, this was yet another relatively small forecasting error on behalf of the NWS and computer models that basically changed the entire outlook of the day.

Looking at the upcoming forecasts for the remainder of the week it looks like we could possibly have a chance of severe through Saturday now. Wednesday looks to maybe have remnant storms form off the warm front that is stalled out over the metroplex in the morning. Thursday has us in the southern fringe of a line of severe storms that may form and move across the Ozarks and Mississippi River Valley. Friday and maybe Saturday could have some severe storms around here, but it is still a few days away so confidence is low.
