Weekend Rain Forecast Still A Question Mark
We have some questions and concerns for the upcoming weekend. What will happen with the moisture from Isaac? What we have noticed is that the track for this storm has been trending farther south each model run. (About every 12 hours). While this trend is being followed by many of our models there are still some outliers. Precipitation forecasts are still very high for the next 5 days across the area. The Hydrometeorological Prediction Center forecast still has heavy rain just south of our area. What we have noticed is that there will be a sharp cut off of moisture north of this low pressure.
In the National Hurricane Center forecast above we continue to see the ‘cone’ of probability extends to southern Michigan. The other thing I noticed today is that the tropical depression is tracking farther south. Because of the sharp cut off in moisture it seems like with this track we stay out of the heavy rainfall. There is still uncertainty with this forecast as the low could move a little farther north, but we are finally beginning to see what we think is a trend moving the heavier rainfall south.
A Muggy Night For Football
Today is another Ozone Action Day, with temperatures in the 90s we will also have have humidity. This muggy forecast will carry over into tonight, so those high school football games will be rather sultry with temperatures staying in the 80s. Humidity will stick around much of the weekend with periods of showers.
