Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 355 AM EDT Mon Oct 20 2014 Valid 12Z Mon Oct 20 2014 - 12Z Wed Oct 22 2014 ***Unsettled weather for the northwestern states*** ***Showers and storms for southern Texas and New Mexico*** ***Rain for the Northeast U.S. by midweek*** An active weather pattern continues across the northwest corner of the U.S. as a cold front currently near the coast continues to move inland early this week. This will bring down snow levels enough to warrant mention of rain/snow showers for the higher elevations of the central and northern Rockies in the progs. Another cold front will approach the Pacific Northwest by Tuesday night and this is expected to bring more rain and high elevation snow to Washington and Oregon. Scattered showers and thunderstorms are likely to develop over southern Texas and into New Mexico for the early part of the week. Moisture flowing towards the northwest from the Gulf of Mexico combined with instability aloft will foster the development of mainly afternoon and evening showers and storms. Things get interesting for New England and upstate New York by Tuesday as a nor'easter develops over the coastal waters of the Atlantic. An upper level disturbance is expected to drop through the Great Lakes into the Northeast, which will result in the development of this storm system. The heaviest rainfall is expected by Tuesday morning for locations primarily northeast of Philadelphia as moisture is advected northward from the Atlantic Ocean. A few inches of rainfall is possible by midweek over New England before the storm departs. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
