11/30 – Rob Knight’s Below Seasonal Temps” Mid-Morning Forecast

Multiple forecast concerns in the next 24 hrs. that will lead to some minor impacts. First issue will be today with strong winds anticipated and then the second issue is a light to moderate freeze across the region tonight. Gusty winds today will have winds in the 20-30 mph range. In addition it looks like we may clear out just a tad faster today which should allow for a little more sun and thus better mixing as well. With that we will issue a wind advisory today for the whole area mainly for wind gusts of around 30-35 mph. Winds should relax near sunset.

As for lows tonight, strong cold air and windy conditions will help keep the region well mixed and thus we will not warm up much from morning lows this morning. With temperatures already that low it won’t take much to get temperatures to fall below freezing in many locations tonight. Forecast lows tonight still show upper 20s to lower 30s for a good chunk of the area. We have upgraded the Freeze watch to a warning now for all of the same locations that were in the watch.

Another strong disturbance will dig south over the continental divide Tuesday, this will induce low pressure over the southern Plains and that combined with our cold departing sfc high will cause return flow to set back up and moisture to return. A consensus of the models brings the next chance of showers into the forecast area Wednesday afternoon. There could be enough instability for a few thunderstorms along the southeast Louisiana coast and mainly offshore in the coastal waters to the south on Wednesday night, then there will be a lingering chance of showers Thursday and possibly into Friday. Temperatures will warm a bit on Thursday before cooling back to below normal levels Friday into the weekend.
