Looks like persistence low level cloudiness will continue across
northern portions with partly cloudy to mostly clear skies across
southern portion of the mid state region well into this evening
and potentially thru the early morning hours on Friday. This will
at least impact lows across northern portions of the mid state
region as they may not fall as far as previously expected despite
surface ridging apex the Texas coastline all the way up into
western Canada continues to usher in a cold air advection air mass
to our area. This weather pattern the result of the evolution in
the upper level pattern to a more zonal flow through tonight. A
weak upper level disturbance will move thru the area on Fri and
start the process of ushering this cloudiness to our east.
It also continues to look like the mid state will remain dry thru
Sat evening as southern portion of above mentioned surface ridging
apex moves into our region. That above mentioned upper level
disturbance passage will result in dry northwesterly flow aloft
per enhanced upper level ridging across the western contiguous
U.S. As Sat progresses, an upper level trough will develop across
the western contiguous U.S. coastline and an upper level wave will
push into central portions of Texas by Sat evening setting the
stage for the next potential rainfall event across our area, as
upper level ridging influences that develop across our area on
Saturday pushes eastward and a southwesterly upper level flow
pattern develops. A surface front will also develop across the
northern Ohio River Valley Region stretching westward into the
central plains by late Saturday night.
There could possibly be a wintry mixture on the leading edge of
this moisture advection plume coming in from our southwest late
Saturday night across cntrl and western portions of our region.
Otherwise, it looks like liquid pcpn will be the norm as Sun
morning progresses with moderate showers possible. Lingering
chances of light rainfall with highest potential east are expected
on Sunday afternoon. Model solutions from Sunday night thru the
afternoon hours on Tuesday differ in how much moisture will be
across the mid state region and the potential of instability and
lifting dynamics in place, factoring in difference in timing and
areal coverage potential too, as a southwesterly upper level flow
pattern persist. That above mentioned surface front is expected
to push finally push thru our area late Sunday night into the
morning hours on Monday. Will thus address the Sunday night thru
Tuesday afternoon time frame weather pattern as unsettled and
continue a mention of isolated to scattered light rainfall across
our area during that period.
Another surface frontal along with an associated upper level
trough passage from our northwest is expected as the afternoon
hours progress on Tuesday, resulting in yet again dry conditions
coming to the mid state region in association with a dry air mass
originating out of the midwest becoming established across our
area by Wed morning. The surface high pressure pattern associated
with this air mass will shift to the east thru Thursday, resulting
in once again a more southerly surface flow pattern becoming
established with yet another pcpn event being possible across the
mid state region late next work week. So to sum up, expecting
Tuesday night thru Thursday to remain dry.
As for temps, seasonally cool temps expected tonight thru Fri
night will become more seasonal as the weekend progresses.
Lows tonight will be in the mid 20s, highs on Friday will mainly
be in the lower 40s, upper 30s to around 40 Cumberland Plateau
Region, with lows Friday night in the mid to upper 20s.
Overnight lows and afternoon highs are expected to warm to 10
degrees or more above seasonal normal values. Afternoon highs
on Tuesday will mainly span the upper 50s. This seasonably warm
pattern looks like it will continue thru late next week too.
