6/17 – Night Rob’s “Actual Temps Near 100 Saturday” Friday Night Forecast

Gulfport tied a record-high today at 95, and Pascagoula hit 99, which was one degree under their record of 100 (they have a shot at 100 Saturday). Mid-upper 90s today will repeat Saturday, keeping that heat advisory up. Remember heat is cumulative, making it very important to get to a place it is cool for a while each day, especially during the hottest part of the day. We could even be getting near heat warning criteria for Saturday (real feels of 113), and isolated locations may touch some of these figures. There a couple of weather players this weekend.

One is the expansion of the southwest high pressure area upper high to the east, setting up across the central part of the country (very early this year, normally see this in mid-late July/August). The next is the flow will be northerly from surface up, and this time of year is when a light northerly flow actually causes temps to rise. The last thing is there will be some slightly less-humid air moving in, which will also allow temps to heat up more than normal. We will keep temps below the triple digits for now but will keep it in mind that the breaking of this 100F figure is entirely possible Saturday for at least one or two sites. These figures area-wide will be very close if not breaking record highs for this time of year.

A weak cold front will approach from the northeast in back door fashion on Saturday.  Latest forecast trends are now suggesting this could trigger scattered thunderstorm late-afternoon Saturday, so we’ll go with a 20% chance there. But, the main impact of this front will to be to temporarily lower humidity for Father’s Day Sunday. Although it’ll still be hot, Sunday will be noticeably more comfortable than Saturday.
Humidity starts to return on Monday, along with another hot work week expected…again with possible heat advisories. Monday and Tuesday won’t be the worst of days, but late-week the heat will be on again. Specifically next Thursday and Friday, some analysis is suggesting close to 100 degrees again. Usually it is fairly hard to hit 100 down here, especially this early on in the summer, however models have been fairly consistent with this trend so I would not be surprised to see some areas crack the triple digits. This would again put real-feels in the 110°range.
