Forecast Discussion

- Showers/scattered storms today, then dryer and less humid

Latest surface analysis shows low pressure over eastern Ontario
with water vapor imagery depicting a similar location for the
upper low. Minor short waves were seen in the water vapor
rotating around the upper low and these are progd to move across
the eastern cwa today.

Today will be the last we see of rain for much of the upcoming
week and will be similar to yesterday...just a bit farther east.
Instability this afternoon will be less than the last few days but
500-700 j/kg MUCAPE will be enough to support a few non severe
storms as we go through the peak heating of the afternoon. Look
for an uptick in showers/storms beginning early afternoon mainly
east of US-131. The precipitation will wane during the evening as
atmospheric stability increases and the influence of the upper low
decreases as it moves east.

High pressure will begin to move in tonight as drier air advects
south from Canada. Today will be another humid day as dewpoints
will remain around 70, but will fall into the 50s by Monday
morning. Clearing skies tonight will lead to partly sunny skies
Monday.

- Below normal temps into Wednesday, warming trend starts Thursday

Decent agreement amongst the models exists with keeping a deep
northerly flow across the region through Wednesday.  As a result
relatively cooler air from Canada will funnel down into the Great
Lakes region during this time.  Ensemble temperature plots are
fairly tight so decent confidence on the cooler than normal
temperatures exist.  A positively tilted mid level ridge approaches
from the west Thursday and tracks through the area on Friday.  Based
on this, a warming trend will develop and above normal temperatures
may arrive by Friday.  Nearly all ensemble members show no QPF so we
will keep the Tuesday through Friday period dry.

The landscape appreciated yesterday’s rain.

I went on a bus trip to Detroit yesterday and seen the Tigers play the Yankees yesterday. The weather was much better than I thought it would be. In fact it was very good for the game with just some light mist falling near the start of the game and the sun came out. The Tigers won the game 4 to 0. On the trip home there were some heavy thunderstorms near Lansing and there was a nice rainbow at the rest area we stopped at. All in all, a great day.
