Area forecast discussion
National Weather Service Saint Louis MO
230 am CDT Sat Jun 24 2017

Short term... (through late tonight)
issued at 229 am CDT Sat Jun 24 2017

A longwave trough covering the central and eastern Continental U.S. Will
provide a period of below normal temperatures to the area this
weekend and early next week. Precipitation chances still appear to
be minimal on Sunday despite a weak shortwave and passage of a
reinforcing cold front. The only model showing any quantitative precipitation forecast/simulated
reflectivity behind the front is the experimental hrrr at this time.


Long term... (sunday through friday)
issued at 229 am CDT Sat Jun 24 2017

The cool and dry pattern will break next week as the upper level
pattern becomes more zonal on Tuesday and then transitions to a
southwest flow toward the later part of the week.

Cloud cover will be on the increase Sunday night and Monday with a
good chance of showers occuring with warm advection in the morning
and/or the cold core shortwave in the afternoon. Otherwise, warmer
temperatures near seasonal averages, are expected to return by
midweek with chances of thunderstorms steadily increasing each day
from the north. Greatest probability of widespread rainfall across
the majority of the County Warning Area appear to be next Friday/Friday night.



Aviation... (for the 06z tafs through 06z Saturday night)
issued at 1144 PM CDT Fri Jun 23 2017

VFR conditions are expected for the majority of the valid taf
period. Winds will remain northwesterly to northerly. Lower dew
points have been filtering into the region over the last several
hours which will inhibit widespread fog formation. However, the
dew point depression was lower at KUIN than at other sites at taf
issuance, and it is possible that a brief period of light fog may
develop there near daybreak.
