DISCUSSION.

Amplified 590+dm subtropical ridge anchored off the East Coast and a closed low over the southern Great Plains will drive warm, humid air into the Great Lakes region for the next several days. This consolidated corridor of southerly flow extending from the Gulf of Mexico into northwest Ontario will drive episodic convection upstream which the NWP indicate will result numerous shortwaves, some convectively enhanced, lifting through the CWA between now and Thursday. The first two are already evident on regional imagery with modest ascent associated with the lead wave supporting convection within a localized area of enhanced boundary layer convergence over far western/northwestern Lower early this afternoon. As destabilization continues over the remainder of the peninsula, additional pulse convection can be expected within any stronger HCRs and/or especially over the Thumb where isentropic ascent will be maximized by later this afternoon. The next wave, presently positioned along the I-70 corridor in IL/IN will follow roughly the same trajectory, though slightly further west and later in the peak heating cycle. Therefore, some additional activity near the Ohio border late this afternoon before diminishing around sunset. Elevated dewpoints will keep a high floor on overnight lows in the mid/upper 60s, around 15 degrees above late May average values. Hedged slightly lower with low temps over the southern portion of the CWA as dry air noted on ch 10 and surface obs over the Appalachians will lift through that area during the first half of tonight. Greater depth of dry air in the lower atmosphere may allow dewpoints and temps to fall off an additional couple of degrees.

Little change on Wednesday with the exception of a greater coverage of mid-level clouds as a portion of the wave over the far southeast US is steered through the area within deep southeast flow. Greater clouds and stronger southeast flow over Lake Erie will limit instability over at least the southeast half of the area, thereby limiting isolated afternoon pulse t-storms to western counties.

By late Wednesday night, a northern stream wave will impinge on the resident subtropical ridge as it approaches the Dakotas. As the nascent right entrance region takes shape over portions of the Upper Midwest late Wednesday night moisture advection and increasing isentropic ascent will be underway locally, first in response to the remainder of the energy over the southeast US lifting into the area early Thursday and then as the closed low itself is absorbed back into the westerlies. The initial slug of forcing Thursday morning will lead the development of any substantial instability thereby keeping QPF in check through the first half of the day.

Attention then turns to the strengthening right entrance region and the attendant low-level frontal response as the closed low progresses toward the Bootheel of Missouri during Thursday. A 12-18 hour period of strong deformation will strengthen the frontal zone as deep layer flow becomes increasingly boundary-parallel. This will slow its forward progress and increase PWATs to 1.5"-1.7" along the front itself. Given the inherent uncertainty in the phase speed of the northern wave and exact behavior of the closed low during the next 48 hours the forecast position of the front - which is currently progged to reside near/north of a Chicago-Saginaw line Thurs/Thurs night - the location of the axis of heaviest rain will be subject to revision going forward. Unlike last week, the duration of any heavy rain threat will be limited by the progressive nature of the aforementioned northern wave.

Canadian high pressure brings choice late spring wx for the weekend. Highs in the 60s and 70s under mostly sunny skies accompanied by dewpoints in the 30s and 40s. Crisp overnight lows.

MARINE.

Moist airmass will plague the region through the end of the work week. This may produce areas of fog, some dense across northern Lake Huron rest of today.

With a stagnant pattern, south-southeast winds generally around 10kts will veer more south Wednesday then maintain that primary direction before veering to the southwest Thursday night as a cold front begins to slowly move through the area exiting Friday afternoon. Winds will veer to the northwest and increase speed slightly after passage and continue through the weekend. In the meantime there will be some degree chance of showers and thunderstorms until the front passes. Overall, wave heights should remain on the low side.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
