Technical Discussion

The purpose of this update is to include the Frost Advisory issued by NWS MOB for early Sunday Morning. I still believe that wind speeds will probably be high enough to preclude much in the way of frost development, but mentioned the possibility of patchy frost just to be safe. Previous discussion follows: Short Term (Saturday through Sunday): Currently, an area of high pressure is located to the northwest of the area, over the Great Plains states. A Weak CAA pattern will continue across the region through the short term period, with cool northerly winds dominating the forecast area around the high. Temperatures will remain below normal through Sunday. Another cold night is ahead with lows dropping down into the mid to upper 30's. However, wind speeds are expected to stay high enough to preculde the development of frost or freezing temperatures at KMOB. By Sunday Night, some return flow is expected to develop across the area as the high pressure area moves toward the Mid-Atlantic states. Long Term (Monday through Wednesday): WAA will dominate the forecast area through this period, with temperatures warming up to near normal levels. The return flow from the Gulf will also result in more moisture moving into the area. By Tuesday, a weak shortwave trough will be located to the west, resulting in W/SW flow at 500 mb. A stronger shortwave will be located across the Upper Midwest. The northern trough will have better dynamics associated with it. However, with moisture in place over MOB, a slight chance of rain will be included for MOB. By Tuesday Night and Wednesday, the southern shortwave will move closer to the area, resulting in some slight PVA over MOB. Included low-end chance PoPs for the end of the period, with a scattered coverage of SHRA/TSRA expected at this time. Highs and lows will continue to warm each day through the end of the period.

Hazardous Weather

The National Weather Service in Mobile has issued a Frost Advisory from 3 am to 7 am Sunday Morning. If wind speeds become calm or very light, some patchy frost may develop during this time frame. Sensitive outdoor plants should be covered or brought inside for protection. Otherwise, no hazardous weather is expected through the forecast period.
