DISCUSSION...

Lengthy quiet stretch of weather continues today as the center of the persistent surface high passes over the Great Lakes this morning. The high will slowly drift southeast through the day and overnight reaching the Mid Atlantic coast by Thursday afternoon. Flow will be light and variable today with only light northerly winds aloft to start the day but the slow drift southward will allow for a weak southwesterly wind to develop later in the day. Looking aloft, the blocking pattern is breaking with a strong wave passing through Canada which will flatten the amplified ridge over the Great Lakes while folding it into the region. This will help develop deeper southwesterly flow which will advect warmer air into the region with 850mb temps rising over 10C, after hovering in the upper single digits for a couple days, which will help boost high temps into the 80s today.

Continued warm air advection and influence of the ridge, will bump temps up further on Thursday into the mid to upper 80s. We'll stay dry yet again with dewpoints possibly breaking 50F in the afternoon which keeps humidity in the 30 percent range. We stay warm on Friday but a slow moving front dropping toward the northern Great Lakes will help focus moisture advecting along it along with remnant convective waves later Friday through Saturday bringing chances of showers and thunderstorms back to the area. This is all coinciding with an upper level trough tracking over Saturday as well. Stacked ridging then moves back in behind the passing front Sunday which should dry us back out. We'll see how long the ridging can hold over the region before stalled troughing west of Lake MI finally pushes east, which may not be til later in the week.

MARINE...

High pressure continues to sit atop the Great Lakes region today into Thursday, then pushing southeastward as a cold front comes through on Friday. North Lake Huron is expecting relatively light winds shifting eastward, while southern Lake Huron, Lake St. Clair and the coast of Lake Erie will experience relatively light winds out of the north. This will then turn into a northerly flow for all marine areas as we approach Thursday into Friday. As our cold front approaches Friday night into Saturday, this will bring us our next chance of rain and thunderstorms along with some breezy conditions over the area.
