.KEY MESSAGES...
- Gradual warm up into Saturday as a ridge moves across the area.
- A cold front Saturday night into Sunday will bring another brief
round of rain showers. Then, another warm up into mid-next-
week.

.DISCUSSION...
WEATHER PATTERN OVERVIEW:
Today through Saturday, an upper level ridge moves across the
region bringing warmer and drier weather for a couple days. Gusty
SE wind is expected ahead of a cold front Saturday night, and
might get high enough to reach Lake Wind Advisory criteria.
Currently this is just happening next to the dam, but could
easily expand in future forecasts.
Saturday night onward, conditions cool off with a cold front
initially saturday night into mid-day Sunday as zonal flow returns
initially. Another brief shortwave will pull rain showers across
the region as well. But then, temps gradually meander upward into
the 80s for highs by Wednesday and Thursday.
FORECAST CONFIDENCE & DEVIATIONS:
No changes to NBM tonight.
&&
.AVIATION...
LAST UPDATE: 0400Z

afternoon. Further veering E Friday night.
