.KEY MESSAGES...

- Showers tonight and Tuesday. Slight chance for thunderstorms
Tuesday afternoon and evening.

- Colder Tue night and Wednesday, then moderating temps.

- Active weather likely this upcoming weekend.

&&

.SHORT TERM /THROUGH WEDNESDAY/...
Pattern/synopsis: Low pressure and an associated surface cold front
will cross the region later tonight into Tuesday.

Forecast: Clouds will increase and thicken tonight. A band of
showers expected to cross the region late tonight into early Tuesday
from west to east. This will be followed by a lull in the action for
much of Tuesday morning. Showers and possible embedded thunder
likely Tuesday afternoon and evening. Instability is weak but looks
like possibly up to a few hundred j/kg of cape across southeast
zones. The airmass remains rather dry however with precipitable
water values only increasing to around a half inch. Surface
dewpoints will be lucky to make it to much above the low 40s
Tuesday. Can`t rule out locally gusty winds and pea sized hail,
mainly as you head down toward Saginaw Bay. In the meantime, high
fire danger and the associated red flag warning continues across all
of northern lower into early this evening due to gusty southwest
winds, very low relative humidity and very dry fine fuels. Lows
tonight in the mild low and mid 40s. Highs Tuesday generally ranging
from the upper 50s north to the mid 60s south.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
PATTERN SYNOPSIS/FORECAST:

A trough swings out of the region and shifts winds from west to
north as a frontal boundary and a cooler airmass push into the area
heading into Wednesday. Heights rise later in the week due to a
ridge of high pressure building across the Plains resulting in quiet
and mild weather for Northern Michigan (potentially leading to fire
weather concerns). However, by the weekend, another shot of energy
is expected to make its way from the Plains to the upper Midwest
resulting in likely active weather for this upcoming weekend.


PRIMARY FORECAST CONCERNS:

Active weather likely this upcoming weekend: An upper-level low and
its associated surface low pressure are expected to track northward
from the central Plains to the upper Midwest. At this time, showers
appear likely, with the potential for some embedded thunderstorms
possible. Looking at guidance, decent CAPE looks to advect into the
region making this setup something to keep an eye on in the coming
days. Accompanying these showers, could be some pretty gusty winds
with some areas potentially seeing gusts up to 40 mph. However, with
this setup being several days away, stay tuned as we continue to
fine tune the forecast.

.AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/...
Initial upstream cold front will swing thru our CWA overnight...
providing sct/nmrs showers overnight into early Tuesday. We
will see a brief break in the action Tuesday morning...before
additional chances of showers and possibly some thunderstorms
develop Tuesday afternoon and evening along and ahead of the
secondary main cold front as it sweeps thru our region Tuesday
night. Prevailing conditions will remain VFR thru Tuesday...dropping
to MVFR at times within some heavier shower activity as well as
Tuesday night behind the cold front. LLWS will develop across
portions of Eastern Upper and NW Lower Michigan late tonight.
Surface winds will remain from the SW at 10 to 20 kts...becoming
SW and eventually W/NW on Tuesday and strengthening to 15 to 25
kts behind the secondary cold front.
