DAYS 1-5 (AUGUST 3-7)
We have a change in the pattern upcoming, but before that a very warm and muggy weekend, continuing the ongoing mid summer theme. Today’s shower and thunderstorm threat was greatest before I wrote this, with a decent batch of showers and embedded storms moving through a good portion of the region in the pre-dawn hours, but during the day today, the activity will be limited to isolated. It is later tonight, a disturbance can send another batch or two of showers/storms through the region. During Sunday, an approaching cold front will up the chance somewhat, but it still doesn’t look like the region will be wide-swathed by showers and thunderstorms. Just keep in mind your chance of seeing one is better tomorrow than today. Temperatures will be higher today with more sun, and generally down a couple degrees on average tomorrow due to more cloudiness prevailing. Monday, a more westerly wind sets up another down slope situation, which will cause me to bump my temperature forecast up over what I had on yesterday’s update. The shower and thunderstorm chance is lower Monday, but not non-existent. Monday will be the last day of heat for a while as we settle into a cooler regime as we head through Tuesday and Wednesday with more northerly to easterly flow setting up with the help of Canadian high pressure. However, the frontal boundary that approaches Sunday and passes Monday is not going that far, and will be sitting nearby, allowing the weather to be somewhat unsettled at times heading toward midweek. Details of this will be brought into focus as we get closer to that time frame.

DAYS 6-10 (AUGUST 8-12)
A tropical system (forecast to be a tropical storm) in the US Southeast region will have to be watched for possible East Coast impact. The possibilities with the eventual track and impact of this system are very wide-ranging, and it’s forecast-foolish to try to pin it down with confidence this far out. Therefore, my sensible weather outlook for this period of time is for near to below normal temperatures as a result of the upcoming pattern, and an opportunity for some rainfall at some point, to be fine-tuned in the days ahead. Don’t alter / cancel any plans for this period of time just yet – instead, keep in mind that this may need to be considered if the system has impact.
DAYS 11-15 (AUGUST 12-16)
No major sustained heat indicated, fairly seasonable and a few shower and thunderstorm opportunities anticipated as we head through mid month.
