.SHORT TERM /THROUGH TONIGHT/...
Issued at 200 PM CDT Fri Apr 11 2025

Surface high pressure sliding overhead tonight will lead to light
and variable winds, and chilly temps with lows in the 30s.
Favored low-lying cold spots to the north and east of the Quad
Cities may bottom out near freezing, so if you have any potted
plants outside you may want to cover them or bring them indoors.
Based on local climatology, it`s too early in the spring season
to issue any frost/freeze headlines.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 200 PM CDT Fri Apr 11 2025

An upper level ridge will shift eastward into the region over
the weekend. Attendant height rises will foster a broad
warm advection regime. Accompanying southerly surface winds
will become gusty both Saturday (west of the Mississippi) and
Sunday (area-wide mainly in the morning). This coupled with
ample sunshine will boost highs well into the 60s and 70s.
Winds don`t look to be too much of a hindrance, and in fact
seeing more consensus toward a surface low approaching
by Sunday afternoon to slacken the gradient and ease any fire
weather concerns. The surface low is attendant to an advancing
a progressive shortwave trough that will shift from the
Pacific Northwest early in the weekend to the Great Lakes region
by late in the day on Monday. Elevated moisture advection
late Saturday night and Sunday in advance will lead to shower
chances (20-30%), and possibly isolated thunder, mainly north
of Hwy 30. Prior to the shortwave moving into the Great Lakes on
Monday it will usher in a cold front late Sunday night. Forcing
and moisture look quite limited to support any organized rain
chances. Arriving post-frontal on Monday will be some
additional shower chances with a bout of mid level
frontogenetical forcing in the right entrance region of a 120+
kt Upper Midwest 250-300 mb jet streak. Right now NBM PoPs are
low at ~20% and mainly south, as there will be some dry air to
overcome. In the wake of this system, a period of cooler weather
is on tap heading into the middle of next week, as high
pressure builds in. The threat for near freezing lows and frost
will exist, particularly along and north of Hwy 30 late Tuesday
night/early Wednesday morning where the latest NBM has lows
between 30 to 34 F.
