Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 348 AM EDT Tue Oct 13 2020 Valid 12Z Tue Oct 13 2020 - 12Z Thu Oct 15 2020 ..A slow moving area of low pressure will bring moderate to heavy rainfall to portions of the Northeast through Wednesday morning... ...A fast moving system will bring heavy precipitation to the Pacific Northwest and Northern Rockies on today with heavy snow for the northern Washington State Cascades and Northern Rockies of Montana... ...Above average temperatures across much of the nation over the next two days will be followed by the beginning of a significant mid-week cool down across the Northern Rockies/Plains on Wednesday... A slow-moving area of low pressure, which is currently gliding along the northern Mid-Atlantic coast, will continue its ascent into the Northeast coast on Tuesday, where it will bring a broad area of moderate to heavy precipitation from eastern New York State, across all of New England. Much of this region has been dry over the past month, with rainfall 2 to 4 inches below average. In contrast to the slow moving coastal low along the northeast, a very fast moving area of low pressure and its associated front will enter the Pacific Northwest and Northern Rockies today. Heavy precipitation is likely across the Pacific Northwest and Northern Rockies with this system, along with high elevation heavy snow for the northern Washington State Cascades and Northern Rockies of Montana. This area of low pressure will continue to move quickly eastward across the Northern Plains into the Upper Mississippi Valley Tuesday night into Wednesday. Precipitation amounts are expected to be lighter across these areas Tuesday night into Wednesday, and confined to areas along the border with south central Canada. This system will begin to restrengthen ahead of an amplifying upper-level trough and produce more measurable rainfall for the Upper Great Lakes region Wednesday night into Thursday. Temperatures over the next two days will be mostly above average across the nation, with exceptions being across the above mentioned areas that will see precipitation. The most anomalously warm temperatures will be across the sunbelt and the Southern to Central High Plains on Wednesday where temperatures will be hot enough to potentially set record highs for those areas. This heat paired with dry and windy conditions will lead to the Elevated Risk of fire weather today and Wednesday. A Critical Risk of fire weather is in place for parts of the Southern Plains, in particular, on Wednesday as the upper-level trough deepens along the foothills of the Rockies which will in-turn tighten the pressure gradient and lower dew points across the area. However, the first signs of a significant mid to late week cool down will appear across the Northern Plains on Wednesday in the wake of the fast moving area of low pressure and its associated cold front. These below average temperatures will plunge southeastward mid to late week across much of the central to eastern U.S. Kebede/Oravec Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
