From the WABI-TV5 & CW Forecast Center:
Over the weekend the large upper low that has been bringing the wet weather to the Ohio River Valley and the Mid-Atlantic States the past few days will begin to drift northeast while at the same time weakening. The weakening upper low will bring the risk of a few scattered showers to especially southern parts of Maine as we head through the weekend, with later Saturday through early Sunday having the best shot of seeing a little light shower activity in our region. High temps over the weekend will mostly run in the mid and upper 50s over southern and coastal Maine, with temperatures running in the 60s over interior portions of central and northern Maine. The chance for scattered showers will continue on Monday as the upper level low moves through the Northeast.
Over the next several days all weather eyes along the East Coast will be watching the progress of Hurricane Matthew as it moves through the Caribbean Sea. Many of the computer models bring the hurricane north just to the east of the U.S. East Coast late next week and that could cause problems for some portion of the East Coast either late in the workweek or next weekend, but it way too early to tell what if any impact the storm will have on New England. The eventual track of Matthew will be determined by a trough of low pressure approaching the east coast later next week and whether the trough captures Hurricane Matthew and pulls it north to northwest along the Eastern Seaboard or whether it helps to push it out to sea to our southeast. The exact configuration of the trough will determine which track the storm takes and it will likely take several more days until we have a better idea, so stay tuned to the WABI-TV5 and CW Forecast Center as we head through next week.
