Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 208 PM CDT Mon Oct 18 2021

SHORT TERM. 208 PM CDT

Through Tuesday night .

Benign weather will continue. Tuesday will be a near carbon copy of today, expect with the addition of some cirrus and a bit stronger of a southwest breeze.

- Izzi

LONG TERM. 208 PM CDT

Wednesday through Monday .

Guidance remains in good agreement in moving a fairly compact, but impressive closed mid-upper level low and associated shortwave trough across the region later Wednesday into early Thursday. If anything, compared to yesterday guidance is even slower moving the ridge of high pressure along the Gulf Coast eastward. The result will be even less opportunity for moisture return in advance of the midweek system. Given the magnitude of forcing and fairly steep mid level lapse rates, still expecting scattered showers and perhaps some isolated thunderstorms ahead of the cold front. The limited moisture return should keep precipitation totals pretty modest, with many areas probably ending up with less than a tenth of an inch.

Medium range models are have been wavering some with respect to the details of the evolution of the pattern this weekend. Still pretty good agreement in the the general idea of long wave troughing over eastern North America and into the Great Lakes. However, it gets more complicated with how quickly this trough moves east with latest runs suggesting some blocking developing which could keep the cooler conditions around longer. At this point, with medium range models not quite ready to commit to a solution, didn't make any changes to the blended model guidance. Very low confidence in precipitation chances over the weekend, but if it rains, Sunday looks more likely than Saturday. Wouldn't be hard to envision further changes to guidance in the next couple of days as medium range models attempt to resolve complex pattern.

- Izzi

AVIATION. For the 18Z TAFs .

VFR through the TAF cycle with generally light southerly winds. A weak lake breeze could develop this afternoon, but if it does wouldn't expect it to reach ORD or MDW. The south-southwest winds will increase a bit tomorrow afternoon with some 15-19kt gusts probable.
