Today will be the hottest day since late July in the Philly metro region as high temperatures likely surpass the 90 degree mark which did not officially happen during the entire month of August. Today may also turn out to be the last 90 degree day of the season as a strong cool front will bring big changes to the region for later this week. That front will arrive in the eastern states later tomorrow and it will bring with it the chance for strong thunderstorms around here containing gusty winds, heavy rainfall and frequent lightning. Following the frontal passage, it’ll turn unseasonably cool on Friday and Saturday with well below normal temperatures and highs struggling to reach the 70 degree mark. The refreshingly cool air mass will last into Sunday and Monday with highs holding in the comfortable 70’s on those days to begin the new week.
Elsewhere, Humberto has indeed become the first hurricane of the 2013 season as it attained that status late last night with sustained winds of 75 mph (category 1). The first half of this tropical season has been very quiet with only one other season since the mid 1940's coming this far without a single hurricane in the Atlantic Basin. Perhaps the tropics will be making up for some lost time as there are other areas of interest in addition to Humberto which is way is closer to Africa than it is to the US. Gabrielle is still a tropical storm in the western Atlantic and it is headed generally northward towards the Atlantic Canadian maritime provinces. A disturbance near the Yucatan Peninsula region of Mexico is likely to intensify into a tropical storm, Ingrid, when it moves over the Gulf of Mexico during the next couple of days on its way towards northeastern Mexico and South Texas.
