October 6 2018
This weekend starts off with low clouds, fog, and some drizzle. This does not show up well on radar, but a few showers have moved in from the Atlantic on coastal Delmarva. The flow off of the Bay has helped with some fog and drizzle in central Maryland and the northern hills into PA as well. Below is a look at the expected cloud cover that will try to thin out this afternoon, but repeat the clouds overnight and Sunday morning. Temps will be moderate but warm back to the 80s and stay there all week.
The other item to watch this morning is a possible Tropical Storm developing in the Gulf of Mexico. This is expected to move north and bring some heavy rain into our region at the end of the week. See more below.

Invest 91 – The technical name for an organizing system entering into the southern Gulf of Mexico. This has a 70% chance for developing to a Tropical Storm in the next 5 days. If so, this would be named Michael. Often there is a second surge of activity in the tropical Atlantic during the month of October.
The reason this is important to us is that it has already changed the long range computer model outlooks. The development and track should pass to our south, but send heavy rain up our way. However, this could pull a cold front through before next weekend, when without this storm it was expected to remain stalled.
The consensus shows intensity reaching tropical storm intensity between Sunday and Tuesday.
The movement to the north, staying just east of Cancun. Then the interaction with a cold front will determine if ion curves to our south or hits us directly.
Forecast Animation (one possibility)
Should this storm develop, we get a change in our forecast to bring in more rain Wednesday and Thursday. The GFS model here shows a track over flood stricken South and North Carolina. But the organized system would help to pull the front through and drag in cooler air for next weekend.
We are still in for a warm week ahead. But the drop in temps appears to arrive abruptly. That would be behind ‘Michael. Yes, the result of a tropical storm could bring in lows in the 40s behind it. Stay tuned. I expect some adjustment of the track and timing.
