Today: Clouds will hang tough as low-level moisture remains stagnant over the Mid Atlantic. High temperatures will be only slightly higher than yesterday--in the mid 40s.
Tonight: A weak low pressure system approaches the region from the northwest. There is a very small chance (less than 20%) a few sprinkles/light showers make it into the region. Temperatures will dip into the lower to mid 30s.
Clouds will finally begin scattering out over the region on Thursday, after a large cold front sweeps through the region. Temperatures on Saturday look like they will remain in the mid-upper 30s under partly sunny conditions.
Tropical Storm ZETA giving forecasters a hard Time:
Zeta, the 27th named storm of this incredible Hurricane season, developed back on December 30, and continues to defy physical parameters set by numerical weather models. Forecasters at the Hurricane Center have been scratching their heads over this feature in the central Atlantic, as exhibited by Dr. Richard Pasch's discussion written yesterday afternoon:
ALTHOUGH A WEAKENING TREND SEEMED IMMINENT EARLIER TODAY...AS THE LOW-CLOUD CENTER STARTED TO BECOME EXPOSED...A NEW BURST OF DEEP CONVECTION SUBSEQUENTLY REFORMED NEAR THE CENTER. ZETA HAS THUSFAR REFUSED TO WEAKEN IN...WHAT APPEARS TO BE...A STRONGLY SHEARED ENVIRONMENT. CLEARLY WE NEED AN INCREASED UNDERSTANDING OF INTENSITY CHANGE FOR SYSTEMS IN THE SUBTROPICS SUCH AS ZETA...EPSILON...VINCE...ETC.
Zeta had moved into a zone of immensely high shear (change of wind speed with height) that almost always kills tropical cyclones like Zeta. But it appeared, yesterday, the storm had diverted much of the vertical wind shear away from its center, promoting slight strengthening. Zeta is, however, looking quite ragged this morning, and slow weakening is anticipated as Zeta progresses towards Bermuda.
