Weekend Weather Outlook Warm Air Returns Latest On Tropical Depression 9
After what was a nice cool day with highs barely back to 70 degrees we are starting tonight with mainly clear skies however there are some clouds nearby to the west and south. Temperatures overnight will settle in the 50s to near 60. Clouds will come in during the early morning hours. Radars are nice and quiet tonight and should remain that way through most of Saturday.
We may see some breaks of sun early on Saturday but clouds will dominate. There is a chance for a spot shower scattered around in the afternoon or evening but the vast majority sees no rain. Highs will be in the 70s. Saturday night an upper trough moves through and that could trigger off a shower or thunderstorm during the early morning hours Sunday. Any showers will be gone by daybreak.
Once the system passes Sunday will be mostly sunny with highs in the 80s. The humidity will be higher but it won’t be oppressive. Monday brings another front with sun and clouds ahead of it with the chance for an afternoon shower or thunderstorm. Monday’s highs will be in the 80s. Then in comes the next high to the north with an onshore flow, dry air and sunshine for Tuesday and Wednesday. Highs both days will be just into the 70s.
TROPICAL DEPRESSION 9 CLOSE TO TROPICAL STORM STRENGTH
Late this afternoon an Air Force plane investigation was able to close off a center and we now have Tropical Depression 9. Slow development is forecast to continue and this depression will likely become Tropical Storm Humberto on Saturday. A NOAA plane is there right now and it is finding winds of 40 to 45 knots at flight level so we may have a tropical storm. We will wait to see what the Hurricane Center does with the 11pm advisory.
I didn’t see much change in the models as far as the longer term outlook here is concerned. A deep trough in the Atlantic southeast of New Foundland will likely reach far enough south to turn any systems to the north and then to the east offshore the Carolinas.
Strong northwest winds in New England down to the Northern Mid Atlantic States would argue against any track up the East Coast. A turn to the east does perhaps pose a longer term threat to Bermuda later Wednesday of next week. The only chance of a complication would be if the Atlantic trough were not as intense and somehow misses the tropical system. That possibility seems very low at this time.
MANY THANKS TO TROPICAL TIDBITS FOR THE USE OF MAPS
