6/8 – Night Rob’s “Chance For Storms, Hot Tomorrow” Wednesday Night Forecast

The Moss Point – Trent Lott International Airport (north of Pascagoula) led the way this afternoon with a peak real-feel temperature of 104 degrees.

As expected, more areas reached a heat index of 100+ this Wednesday afternoon. High pressure over the central gulf into Texas continues to keep thunderstorms at bay, but not for long. The heat looks like it will peak on Thursday, with real-feels near 105 in spots. One wrinkle that could derail that forecast is cloud cover if storm activity can arrive earlier. For now we’re going with a legit chance (30%) of some thunderstorms in the afternoon/evening. Expect a similar day Friday. Overnight lows will continue to be quite elevated, bottoming out in the upper 70s for most.

Although widespread severe storms aren’t expected, we can’t rule out the possibility of getting one or two in the Thursday through Saturday time frame; the atmosphere with have a good deal of instability, heat, and moisture to work with.

A surface front will approach the area Saturday, with perhaps the best chance (40%) of widespread storms, but based on most analysis it will stall before it reaches the coast, which is common for this time of year. Sunday is more of an isolated risk, with chances around 20-30% in the afternoon hours. Temperatures will continue to be hot, in the low to mid 90s, through the extended period. Depending on how much convection we see both Saturday and Sunday may affect how high temperatures will get. Afternoon heat index values will remain around 100 or so through Saturday.

Whatever cooling we get from the weekend front will be minimal, with overnight lows maybe dropping to the lower 70s Saturday night. As the front washes out, a hot, humid flow will re-establish dominance almost immediately, with potential for even hotter temps early next week.
