As of 2 am CDT...skies across Middle Tennessee are mostly clear to
partly cloudy as a band of high clouds moves through. Temperatures
at this hour are primarily in the 40s though a few readings have
dipped into the upper 30s towards the Cumberland Plateau. Winds are
light across the region. At the surface, high pressure extended from
the Gulf Coast, across the Southeastern US, and up the East Coast. A
cold front was located from Wisconsin to Iowa and Nebraska, and it
is this front that will slide southeast and bring us a chance for
precipitation Tuesday night into early Wednesday. Aloft, zonal flow
was located overhead while a shortwave trough was observed over the
northern Plains, moving southeast and forcing the front towards
Middle Tennessee.
For today, the main story will be warmer temperatures, dry
conditions, and gusty winds. Afternoon highs should climb into the
70s areawide. Moisture return is expected later today, as in more
like this evening as moisture along the incoming cold front moves in
from the northwest. This afternoon however, dewpoints should stay in
the 30s and low 40s, which will lead to minimum relative humidity
readings in the mid 20s to mid 30s. Combined with winds gusting to
25, maybe 30 mph, there will be elevated fire weather conditions
across Middle Tennessee.
As the front approaches tonight, a broken band of precipitation
should form and move into the area. While there could be a few
rumbles of thunder with MUCAPE of 100-200 j/kg possible at most,
more than likely all that will be observed is showers. No severe
weather should be anticipated due to the lack of instability. In
addition, the main forcing from the upper level disturbance will be
moving across the Great Lakes, resulting in limited lift and thus
the likelihood of scattered/a broken band of showers occuring versus
a more widespread precipitation event along this front. Winds will
weaken prior to the front arrival, and then remain weak yet shift to
the north once the front has passed. With cloud cover in the region,
low temperatures will remain much warmer than recent nights, only
dropping into the low to mid 50s.
For Wednesday, the only main change compared to Tuesday's predicted
weather will be a noticeable drop in wind speeds. Temperatures
should be about the same despite the passage of a weak cold front.
Some forecast guidance indicates a few showers into the day, mainly
along the Cumberland Plateau. However, with most of the forcing
having passed through the region already, am not certain we will
observe much in the way of precipitation lingering after the
front.
