Updated aviation portion for 18Z TAF issuance

SYNOPSIS. Issued at 346 AM CDT Thu Sep 23 2021

Fairly quiet early autumn weather is expected during the next week.

A blocky pattern over the North Atlantic will expand westward, eventually encompassing most of the CONUS by the middle of next week. The forecast area will initially be within an upper trough position, then transition to being near a sharp ridge for the latter half of the period. Temperatures will range from near to considerably above normal. The best chance for precipitation will be early in the period, but that will still probably result in only limited rainfall so amounts for the period will probably end up below normal.

SHORT TERM. Today . Tonight . and Friday Issued at 346 AM CDT Thu Sep 23 2021

Made a few headline adjustments this morning. Extended the Beach Hazard headline through the afternoon as high waves on Lake Michigan will be slow to subside. Also dropped the Frost Advisory for central Wisconsin. The area was a little too far from the ridge axis, resulting in light winds continuing all night. As a result, temperatures were generally still in the low to middle 40s at forecast issuance time.

A deep, mature cyclone will lift northwest into eastern Lower Michigan today, then shift off to the northeast tonight. The precipitation shield from the cyclone is expected to graze the eastern part of the forecast area, but shouldn't make much progress farther west.

A weak low-level ridge will shift across the area tonight, then a strong shortwave digging southeast from the Canadian Prairie Provinces will approach the area Friday. Forcing with the shortwave will be strong, but the rapid arrival of the system on the heels of the prior system won't allow for much return flow of moisture back into the area. Added a slight chance of thunder for the mid-late afternoon Friday given the strength of the forcing and fairly steep mid-level lapse rates, but do not anticipate a severe risk.

Stayed close to the NBM temperature guidance which has been performing well the past couple days.

LONG TERM. Friday Night Through Wednesday Issued at 346 AM CDT Thu Sep 23 2021

Focus of this forecast remains on precip chances Friday night into Saturday, then followed by temperatures.

Friday night through Saturday night . A deep upper trough will be digging into the region and push a cold front across eastern WI on Friday night. The trough will bring in strong dynamics which should be sufficient to generate light to moderate precip even without anomalous moisture present. Some guidance generates instability over eastern WI early in the evening, which combined with the strong forcing, may be enough trigger off a few thunderstorms. Will keep a mention in the forecast. Most shower activity will likely exit by the end of the evening, except for the far north which could see showers linger overnight and possibly into Saturday morning as well. Cool and breezy conditions will move in behind the front, which will likely create hazardous conditions to small craft on the Lake and Bay. Highs on Saturday have cooled a couple degrees. Skies will clear later on Saturday and a surface ridge axis will move in on Saturday night. If winds can decouple, conditions will be supportive for a frosty night, but that's a big if at this point.

Rest of the forecast . The ensemble means and operational models continue to point towards above normal temperatures returning for much of next week. Details change with each model run, but highs on some days could be well above normal. Will stay conservative with temps as some guidance indicates northwest flow could linger into Monday or Tuesday. As mid-level ridge builds over the center of the continent, precip chances should be far and few between through the middle of next week and possibly longer.

AVIATION. for 18Z TAF Issuance Issued at 101 PM CDT Thu Sep 23 2021

High clouds will continue to be in place for our far eastern TAF sites at the beginning of the period, affecting mainly GRB and MTW and continue to stream across the area through the evening hours. A few showers may make it inland across the area this afternoon, early in the TAF period, but the overall chance was low enough to exclude from prevailing groups at this time. Good flying conditions are then expected to prevail from the overnight hours through the end of the TAF period. The next round of lower CIGs and possible showers will likely be Friday evening.

GRB WATCHES/WARNINGS/ADVISORIES. Beach Hazards Statement until 10 PM CDT this evening for WIZ022- 040-050.
