As the strong cold front moves across Florida on Tuesday, it is expected to slow and stall near South Florida by Wednesday night. Easterly winds will transfer tropical moisture over the state; as the moisture interacts with instability, showers and thunderstorms are expected to continue through most of the week. Most of the heavier rainfall to be along the Atlantic coast of Florida--especially in between Jacksonville and Melbourne. Some of these thunderstorms are capable of producing heavy downpours which could lead to localized flooding. A stormy pattern will continue throughout the Pacific Northwest during the short term period as a series of frontal systems will keep precipitation in the forecast. In addition, snowfall can be expected across the higher elevations of the Cascades. By Thursday, as precipitation spreads southward in northern California--some of the higher elevations in this portion of the state could see light snowfall also. A marginal risk of flash flooding in the western portion of Washington is possible with the locally heavy rainfall expected along a cold front moving over the Pacific Northwest on Thursday morning. Sprawling high pressure across the central and eastern U.S. will keep conditions dry for the rest of the week. High temperatures in the northern Plains are expected to be in the mid to upper 70s on Tuesday which is 10-15 degrees above normal. These dry and warm conditions will fuel critical fire weather conditions across the High Plains on Tuesday. A swift moving cold front will bring temperatures back down to normal on Wednesday; however, by Thursday the high temperatures will rebound back to the upper 70s. New England will also experience high temperatures near 70 degrees on Thursday--which is 10-15 degrees above normal. Reinhart Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
