DAYS 1-5 (OCTOBER 1-5)
Into October we go! And the month will open up with a short-lived summer post-script as high pressure slides offshore and delivers anomalous warmth from the southwest today and Friday. Quite a bit of cloudiness greets us this morning as a disturbance passes by but sun will take back over during the day. Clouds make a come-back later Friday as a cold front approaches, set to put an end to the brief return of summery weather. This front can produce a few showers Friday evening before it heads offshore and sets up a cooler (seasonable) weekend. Fair weather is a lock for Saturday as high pressure builds in. Sunday’s weather remains a bit of a question mark as the front will not be that far to the south and will be a running board for an area of low pressure. This low will pass south of our region late Sunday and early Monday while at the same time a trough and associated surface low will race across southeastern Canada, dragging a cold front our way. Guidance has been all over the place regarding rainfall, but for now I am leaning toward just a graze of rain in southeastern areas during the Sunday midday to evening time frame, with a complete miss of this rain area still possible. This energy does not phase with the energy coming along a stronger northern jet stream, so a larger storm system will not occur in our area. The cold front associated with the system crossing Canada will move through our region on Monday with perhaps a passing shower, after which will will have a reinforcing shot of cooler air along with a gusty breeze.

Fair weather and below normal temperatures early in the period then a recovery to milder mid period. Another cold front brings a shower chance then a return to cooler weather toward the end of the period.
DAYS 11-15 (OCTOBER 11-15)
Westerly air flow in a split flow pattern with the northern jet stream controlling our weather here. This pattern is an up-and-down temperature pattern with a couple brief shower chances, otherwise mainly dry.
