Area forecast discussion, Oct 12, 3:34 AM CDT, 11 minutes before
Area Forecast Discussion
National Weather Service Quad Cities IA IL
334 AM CDT Wed Oct 12 2016
.SYNOPSIS...
Issued at 310 AM CDT Wed Oct 12 2016
Showers and isolated thunderstorms continued into the early
morning hours, east of the Mississippi River. An isolated storm in
the Keokuk area produced hail around nickel size. A cold front
extended from southern Iowa into southwest Wisconsin. Temperatures
ahead of the front were in the mid 50s and 60s, with readings
behind the front in the 40s to low 50s.
&&
.SHORT TERM...(Today and Tonight)
ISSUED AT 310 AM CDT Wed Oct 12 2016
The main forecast issues in the short term period are precip
trends and coverage today, as well as frost/freeze considerations
for tonight.
In the near term, showers and isolated storms are forecast to
linger through the early morning east of the Mississippi River.
Otherwise, expect an increasing coverage of showers from west to
east by late morning into the afternoon hours as a strong cold
front pushes through the region. There may a few thunderstorms
southeast aligned with the modest elevated instability, but no
severe storms are expected. High temperatures will likely occur in
the late morning to early afternoon, then fall off into the upper
40s to mid 50s by early evening.
For tonight, expect a clearing sky and light wind with ideal
conditions for frost and freezing temps. Have adjusted the favored
river valley locations down a bit. After collaboration with
neighboring offices, will go with a freeze warning across the
northwest where temps of 32 or below are favored. The warning is
framed by a frost advisory from Freeport, to Davenport and
Keosaqua, where temps of 33 to 35 will be favored.
.LONG TERM...(Thursday through Tuesday)
ISSUED AT 310 AM CDT Wed Oct 12 2016
Thursday...frost/freeze headlines will expire at 9 am otherwise high
pressure will provide wall-to-wall sunshine, light winds and cool
temperatures. Afternoon highs will be in the mid to upper 50s.
Thursday night: High pressure will slip off to the east but models
have slowed the progression northward of warm air advection mid/high
level clouds. This may allow portions of our northern cwa to
experience frost again. For now will maintain the mention of patchy
frost but if skies remain totally clear and light winds then frost
may be more widespread. Lows will range from the mid to upper 30s
north to the lower 40s south.
Friday: Southerly winds and mostly sunny skies will bring a warmer
day to the cwa, with highs in the 60s.
Saturday and Saturday night: Upper level trough and strengthening
westerlies will push a weak cold front into the cwa Saturday
evening. Ahead of the front, southerly winds will pull better
moisture out of the western Gulf. Forecast NAEFS PWATs near 1.50
inches are 2-2.5 standard deviations above normal for mid October.
Models indicate the thermal axis over the cwa with temperatures
pushing into the 70s Saturday afternoon. The combination of a warm
moist airmass and strengthening deep layer shear may allow for
strong to possibly severe storms. The highest pops will be during
the evening associated with the front.
Sunday through Tuesday: Zonal flow will keep temperatures on the
warm side with highs in the 70s to the lower 80s. There will also
be chances for showers and thunderstorms from any disturbances
riding the flow. However, models are inconsistent with regard to
timing/ strength of individual waves so low confidence on when to
raise pops.
&&
.AVIATION...(For the 06Z TAFS through 06Z Wednesday Night)
ISSUED AT 1144 PM CDT Tue Oct 11 2016
Scattered thunderstorms in southeast Iowa will likely brush past the
BRL terminal early in the forecast period. Elsewhere, a cold front
will push through eastern Iowa overnight into early Wednesday
morning, resulting in shifting winds, lowering cigs and scattered
showers and additional isolated early morning thunderstorms. The
best potential for thunderstorms looks to be at BRL early, then
mainly east of the DBQ and MLI sites and is thus not included in
the forecast. Ceilings will likely become MVFR for most of the
morning hours, with periods of IFR conditions possible. Gradual
improvement should take place in the afternoon, with VFR at all
sites with light NW winds by sunset.
