Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
243 PM CDT Sun Mar 29 2020
.SHORT TERM...
242 PM CDT
Through Monday night...
Strong winds continue this afternoon as a slowly weakening 996 hPa
low over south-central Upper Michigan drifts northeastward. 3hr
pressure rises up to 5 hPa within the strong pressure gradient
combined with modest diurnal mixing beneath a stratus deck is
resulting is in W/WSW wind gusts of 45 to 50 mph across much of the
area. The pressure gradient will slowly weaken through the night,
though continued 3hr pressure rises of 2-3 hPa and slower decoupling
due to continued cloud cover should slow the expected downward trend
in wind speeds. NW winds gusting 20 to 25 mph will continue into
early Monday afternoon. As an approaching ridge builds into the area
from the west, winds will shift NE/E off Lake Michigan late in the
afternoon into Monday night.
In terms of precip, isolated light showers or sprinkles remain
possible into early evening within deep cyclonic flow, but
conditions should otherwise remain dry through Monday night.

.LONG TERM...
242 PM CDT
Tuesday through Sunday...
A fairly quiet period of weather is in store into next weekend as
the mid-level pattern slows from a hybrid of weak Omega and Rex
blocking across the CONUS, with the mid-level saddle point over the
upper Great Lakes Tuesday and Wednesday. This supports continued dry
conditions into Thursday and possibly even well into Friday. As the
western trough of the Omega block progresses eastward later in the
week, a cold front associated with the trough will lift northeast
into far west Ontario, dragging a cold front with rain chances
across the area late Friday into Saturday. After a seasonably cold
day in the mid 40s Tuesday, temperatures will moderate to seasonable
values as we flip the calendar to April.

.AVIATION...
For the 18Z TAFs...
WSW/W winds gusting to 40 knots will continue through around 00Z
before gradually diminishing while veering NW tonight. Gusts of 15-
20 knots will continue through much of Monday. A lake-enhanced wind
shift to the E is expected late in the afternoon at ORD/MDW as high
pressure builds in from the west. Otherwise, MVFR ceilings are
expected through the period, with breaks possible on Monday,
especially at RFD.
