.UPDATE...
Issued at 1021 AM CST Sun Nov 19 2017

Did a quick update earlier to raise sky cover for period of partly
sunny skies late AM and early afternoon with sweeping opaque
high cloudiness attendant to approaching low amplitude shortwave.
Once the wave passes will see return to mainly clear skies by mid
afternoon through early evening. Did not make many changes to
highs given the anticipation of increasing solar insolation later
this afternoon, but will monitor for any changes with the delta
on highs being likely lower in most areas by 1-3 degrees if
cloudiness slower to decrease.

ISSUED AT 300 AM CST Sun Nov 19 2017

Lingering clouds far north and east will clear out early this

high temperatures in the 35 to 45 degree range, about 5 to 10
degrees below normal for the date.

keeping temperatures warmer than early this morning. Expect lows
in the upper 20s to low 30s.

.LONG TERM...(Monday through Saturday)

Dry weather will continue through much of the week with variable
temperatures as the upper flow varies from near zonal to
northwesterly at times.

Monday, stronger southwest flow will boost highs mainly into the
50s, back above normal for late November.

Tuesday and Wednesday, expect a return to northwest flow with
colder weather and highs falling off into the 30s.

Temperatures will rebound again Thursday into Friday. Have again
boosted Friday`s highs above blended guidance. Prospects for
additional precipitation heading into the weekend are less
favorable, and have only carried low pops Friday night over the
northeast half. This period may well end up being dry.
