Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 351 AM EDT Wed Oct 25 2017 Valid 12Z Wed Oct 25 2017 - 12Z Fri Oct 27 2017 ...Heavy rain for New England and colder air arriving to the Plains and Midwest by the end of the week... A strong cold front is slowly tracking across New England, with a deep flow of moisture ahead of it. The heaviest rainfall is likely to materialize across Maine with 1 to 3 inch rainfall amounts, with isolated higher totals possible as a wave of low pressure develops along this front and intensifies. Some instances of flash flooding will be possible given the atmospheric set-up. Cooler and drier conditions will make it feel like fall again behind the front across the eastern U.S. By Wednesday night, another potent storm system will begin sinking southward from Canada and bring a renewed surge of colder weather for much of the Plains and Midwest over the next few days. Snow showers are likely to develop over the Rockies from Montana to Colorado, and another area of snow is expected over parts of the eastern Dakotas and Minnesota as the surface low develops over the Upper Midwest Friday morning. Windy conditions behind the front will make it feel quite blustery. Elsewhere across the continental U.S., fire weather concerns will begin to wane across southern California through the end of the week as the Santa Ana winds abate and cooler temperatures arrive. Cool and dry conditions are expected for most of the Intermountain West through the end of the week. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
