for 18z tafs
/issued 1042 am CST Wednesday Jan 28 2015/
the current short term forecast is in good condition this morning...
with only minor changes required to sky cover grids. Overall...a
beautiful day is in store for the region...as middle-level shortwave
ridge axis approaches from the west. Although morning low stratus
clouds have dissipated...at least some cirrus will spread over the
area in northwest flow aloft and have increased afternoon sky cover
percentages just a bit to account for this. Otherwise...temperatures
will warm rather quickly early this afternoon -- aided by return flow
in warm sector of deepening surface cyclone over the Missouri Valley.
Highs may actually end up being a degree or two warmer than
forecasted values in portions of the forecast area...but not
significant enough to make major changes to the temperature grids.
Updated forecast products have already been transmitted.
for 18z tafs...high pressure gradually moving east across the Ohio Valley
will maintain VFR conds well into the overnight hours...with predom
just some lingering high clouds. Lower clouds...with bases at or above 5-7k
feet will then begin to overspread the region from the west-northwest late Thursday
morning...as a weak cold frontal approaches the area during the day.
