Nice Sunday Through Thursday Warmer Later This Week
Latest on Hurricane Teddy Tropical Storm Beta
JOE & JOE WEATHER SHOW SUNDAY 9/20/2020
Another nice day is underway across the Northeast and Middle Atlantic States. After a very chilly start we are seeing sunshine. We do have an upper trough moving through today and that could produce a few fair weather clouds. It is going to be a very cool day with highs just in the 60s and some inland areas will barely reach 60 degrees. This brings an end to the last weekend of summer with Autumn officially arriving Tuesday. Even though we do have an upper trough moving through, the air is very dry and no showers are forecast. The radars will be quiet.
Tonight will be another very chilly night and another night of frosts and some freezes north and west of the coast and the big cities. Light winds and clear skies set the stage for solid raditional cooling conditions. Lows in many areas just north and west of the big cities will be in the 30s. Warmer urban and coastal areas should bottom in the 40s.
High pressure will be overhead on Monday with sunshine but it will be another cool day ahead. The high to the north will be interacting with Hurricane Teddy which will be passing east of Bermuda during Monday. Northeast winds will keep things cool and the surf will be rough along coastal areas with higher than normal tides and seas up to 12 feet. Beware if you head for the shore for a late season swim. High temperatures will be in the 60s.
Tuesday sees a transition as the high drops southward into the Ohio Valley. Teddy races northward toward Nova Scotia. Tropical Storm Beta by this time should be inland with heavy rain being the biggest threat. We sit in between with lots of sunshine, a northwest wind which brings in more dry air and highs in the 60s to near 70. Warmer temperatures move in Wednesday and Thursday with sunshine both days. Wednesday’s highs will be in the 70s and Thursday we will be in the 70s to near 80. Other than a weak frontal passage on Friday for which at worst there will be a passing shower, we may have to wait until next week to see any widespread rainfall.
HURRICANE TEDDY HEADING NORTHWEST, WILL PASS JUST EAST OF BERMUDA
There has been no important change in the track of Hurricane Teddy. It is about to turn to the north and that should cause the core of Teddy to pass east of Bermuda by 100 or so miles on Monday. Teddy has degraded on the satellite overnight and is not nearly as impressive. Winds are down to 105 mph, a category 2. The hurricane is being impacted by a frontal boundary to the northwest as well as an upper trough distorting the wind field. From Bermuda it heads to Nova Scotia later Tuesday into Wednesday and a transition into a post tropical cyclone.
In rthe Gulf of Mexico we have Tropical Storm Beta and here too overnight Beta is not very well organized. It has a sheared look to it and most of the rain continues to be north and northeast of the center. Heavy rain is the biggest threat here. Beta is forecast to move westward and eventually head into the Texas coast but it is not forecast to strengthen into a hurricane due to the strong wind shear that will continue to inhibit development.
TROPICAL STORM BETA MEANDERING IN THE NW GULF OF MEXICO
8AM LOCATION…27.1N 92.8W
ABOUT 200 MI…320 KM SE OF GALVESTON TEXAS
MAXIMUM SUSTAINED WINDS…60 MPH…95 KM/H
PRESENT MOVEMENT…WNW OR 290 DEGREES AT 3 MPH…6 KM/H
MINIMUM CENTRAL PRESSURE…997 MB…29.44 INCHES
The slow movement continues to mean 10 inches or more of rain along and north of the storm track. Heavy rains which have been confined to Southern Louisiana should begin to spread westward with the storm tracking in that direction. Not much is occurring south of the center and that is likely to remain the case with the storm in this sheared condition. Eventually the system will rain itself out in the Western Gulf States as the upper flow there remains weak.
