The Return of the WCAR
All model guidance is pointing to the return of the Western Central Atlantic Ridge... Latest 12 Z ECM shows the WCAR ...
The ECM starts building this WCAR into the region around 96 hours out and the east coast comes under control of high pressure thru about 168 hours.
Meanwhile the 12 Z GFS also shows the WCAR and the east coast coming under its influence..However..the GFS swings a backdoor cold front across the region...starting about 132 hours out..
What about teleconnections? What do they show us? NAO is neutral, expected to go positive and pretty much stay between neutral and positive thru out the period.
PNA is quite positive now..but expected to go neutral negative .
EPO positive but expected to go to negative & neutral thru the period...
All and all teleconnections are pretty much in agreement with the models. Trough is in the process of lifting out over the next couple days and by the beginning of the week ..ridging will start to move in from the western atlantic while a trough forms in the center of the country. So the next 7 days will be pretty much controlled by ridging and high pressure and then between 7-10 days a cold front with advancing trough will swing thru the region and bring temperatures back down to seasonal to below seasonal levels. Over the next couple days temperatures will be seasonal to slightly below but with a moderating trend and then starting around tuesday of next week depending where you reside temperatures will then become seasonal to above seasonal levels...
