Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 454 AM EDT Tue Oct 01 2013 Valid 12Z Tue Oct 01 2013 - 12Z Thu Oct 03 2013 ...Unsettled weather continues from the Pacific Northwest to the Northern Rockies... ...Conditions will remain favorable for scattered convection along the Gulf Coast and up into the Lower Mississippi Valley... Weather will remain unsettled across the Pacific Northwest the next few days where impulses of energy aloft will continue to bring surges of moisture inland. Although precipitation will not be as widespread and intense as earlier in the week...moist upslope flow against the terrain will help produce some moderate to heavy rains along the coastal ranges and Cascades Tuesday and Wednesday. Late in the forecast period...as a piece of energy impacting the Pacific Northwest amplifies over the Northern Great Basin...some heavier precipitation will get started over northwest Wyoming and up into Western Montana. Temperatures should be low enough to support accumulating snows in the higher elevations of the Washington Cascades and Northern Rockies. Showers and thunderstorms will be possible along the Gulf Coast and across the Lower Mississippi Tuesday and Wednesday...underneath a weak disturbance aloft. Although convective activity should be scattered in nature...plenty of moisture in place across the region could lead to heavy rains within developing storms. The southern tip of Florida will also remain active with showers and thunderstorms the next few days. Farther north...precipitation should begin breaking out along a frontal boundary stretched through the Central Plains and Midwest Wednesday evening as Gulf moisture gets pulled northward ahead of the amplifying energy in the Northwest.
