FORECAST UPDATE: Expect A Bitter Cold Start To 2018!
A much colder airmass will move into our region on New Years Eve with a prolonged period of much below normal temperatures expected to remain in place thru at least Friday of next week. Overnight lows will be especially cold with all but the immediate coast areas likely dipping into the low to mid 20s each night. Even along the immediate coast some temperatures in the upper 20s will be possible. The coldest temperatures should occur Monday night (early Tuesday morning) & Tuesday night (early Wednesday morning) - temperatures will fall into upper teens to near 20°F for interior southeast MS and areas west of I-65/north of Hwy 84 in southwest AL with 20s expected down to the coast. Overnight lows will continue to fall into the low to mid 20s over interior areas each night Wednesday thru Friday with low 30s along and just inland from the coast. Daytime highs will likely be substantially below normal, struggling to make it out of the 30s on New Years Day. Highs on Tuesday will only rise into the upper 30s to mid 40s across the region.
WIND CHILL temperatures will be brutal on New Years Day morning and continue through mid to late week. The "feel like" temperatures could dip as low as the single digits at times north of Highway 84 in Alabama and over most of interior southeast Mississippi from early New Years Day morning through Tuesday night. Winds will be a little less gusty later in the week, but Wind Chill values will likely still range from the upper teens to the upper 20s.
There will be a chance of light precipitation across the region late Saturday night continuing through Sunday evening as the cold airmass arrives. This precipitation will be mainly in
the form of a cold rain across much of our area. However, there
is still some potential that a brief period of a wintry mix (light freezing rain and sleet) could occur over a small portion of
our northwestern counties, primarily near Choctaw County in AL, from late Sunday afternoon into Sunday evening. Any wintry precipitation is expected to end by late Sunday evening. NO ACCUMULATION are currently expected.
