Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 208 PM EDT Sat Oct 18 2014 Valid 00Z Sun Oct 19 2014 - 00Z Tue Oct 21 2014 ...Rainfall across the Pacific Northwest... A slow-moving cold front moves towards the Pacific Northwest on Sunday which will begin another round of rain and thunderstorms to parts of the Northwest and northern California from late Sunday into Monday. Rainfall should be most persistent over the higher terrain of Washington and Oregon, and given the warm nature of this system, any snow would be confined to mountain peaks. Above normal temperatures are expected across much of the Rockies and Great Basin ahead of the cold front. Scattered showers, with some snow at higher elevations, are likely across the Lower Great Lakes and the western slopes of the central and northern Appalachians through Sunday morning as a disturbance aloft pivots across the region. A reinforcing cold front at the disturbance's leading edge is expected to reach the East Coast by this evening. Limited shower/thunderstorm activity is possible across Florida as the boundary drops southward. An invading disturbance from the west brings additional showers to the Great Lakes from late Sunday into Monday. Overall, below normal temperatures expected over the Great Lakes, Ohio Valley, and Northeast over the next couple of days. Parts of southern and western Texas along with New Mexico should witness scattered showers and thunderstorms for the remainder of the weekend as moisture increases and moves onshore from the Gulf of Mexico and a pocket of cooler temperatures aloft moves near the Mexico/United States border, which destabilizes the atmosphere.
