1/30 – Payton’s Wednesday Afternoon Forecast

Weak high pressure centered over northern Louisiana early this morning and to the north, a cold front along Interstate 40 serves as the leading edge of a brutally cold airmass associated with an Arctic high pressure centered over the eastern Dakotas. For South Mississippi temperatures will climb into the lower 50s this afternoon with a light north breeze. Tonight will be another cold one with clearing skies so bundle up! Temperatures are expected to remain above freezing.

The polar vortex currently centered over the Great Lakes will gradually shift northeast into Quebec and then the Canadian by Friday, as the northern Plains States high pressure gradually shifts eastward by Friday. A weak system will bring a few patches of light rain, especially on Friday, but most will be dry.

Onshore flow will continue to pump warm air and moisture into the area through the weekend into early next week with increasing chance for showers and t-storms. At least through the first half of next week, we don`t anticipate any frontal passages, but there will be a day to day chance of precipitation. Temperatures will be well above normal, especially for Sunday through Tuesday, when readings will almost certainly average 10-15 degrees above normal, with highs likely well into the 70s for most areas.
