Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 430 PM EDT Mon Oct 03 2022 Valid 00Z Tue Oct 04 2022 - 00Z Thu Oct 06 2022 ...Rainy, breezy, and cool conditions expand from Mid-Atlantic to southern New England coast... ...Showers and thunderstorms expected across much of New Mexico... ...Above average temperatures forecast for the West Coast, Great Plains and Mississippi Valley... A stagnant upper-level low will slowly rotate from the Mid-Atlantic coast into the western Atlantic over the next couple of days. Showers and thunderstorms will slowly spread across the Mid-Atlantic coast today before shifting northward into parts of the New Jersey and New England coasts on Tuesday. The prolonged nature of this rain event may cause coastal flooding from southeast Virginia up into Long Island where Coastal Flood Advisories and Warnings are in effect. Cool and breezy conditions are expected to continue due to clouds and northerly flow into the region paired with a sharp isobaric gradient along the coast. High temperature records may be tied or broken across the Mid-Atlantic coast on Tuesday as highs fail to make it out of the 50s. Elsewhere, shortwave energy will supply sufficient moisture and instability to support shower and thunderstorm activity across much of New Mexico through Tuesday. Isolated flash flooding is possible over susceptible land surfaces. Light showers may focus along a weak cold front which is forecast to move through the Northern/Central Plains on Tuesday. An amplifying upper ridge will keep things clear and warm across much of the West with high temperatures likely to be between 10-20 degrees above average over the next few days. An upper trough swinging through the mid-section of the country will draw warm southerly air into the Plains and Mississippi Valley through Wednesday. Kebede Graphics are available at
