03/29 – Brantly’s “Warm” Sunday Night Forecast

0

The front that passed through the area had a bit more of a punch than what most weather models had expected, and this resulted in a much drier air mass moving into the region. Dew points have ranged from the mid 40s into the lower 50s for most areas, and this resulted in much lower humidity values throughout the day. Given these dry conditions, rainfall is not expected through Monday morning across the area.

The front itself has pretty much dissipated along the Louisiana coast this afternoon, and a gradual return to onshore flow is expected tonight into tomorrow. These southerly winds will develop in response to another low pressure system moving into the southern Plains tonight and tomorrow. Dew points should slowly rise tonight, and then surge back into the lower to middle 60s for most areas by tomorrow afternoon as moisture flows in from the Gulf. Temperatures should cool into the upper 50s and lower 60s by daybreak tomorrow, and highs should be warmer than average in the upper 70s and lower 80s.

The low pressure system in the southern Plains will push eastward across the Lower Mississippi Valley tomorrow night and then move into the Carolinas by Tuesday afternoon. We could see the development of showers over the northwest and northern portions of the forecast area tomorrow afternoon and evening, but the threat of thunderstorms through the evening hours will be close to zero.

Tuesday will see rapidly improving conditions as the front races to the east. The front should be clear of the area by mid-day, and clearing skies and lower humidity values are anticipated by Tuesday afternoon. Cold air on the back side of the front will be delayed, and a westerly winds will support another warm day with highs climbing into the lower to middle 80s. The cold air will finally push into the area by Tuesday night. Temperatures should cool into the upper 40s and lower 50s which is actually closer to seasonal norms for this time of year.
