Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 251 PM EDT Mon Sep 25 2023 Valid 00Z Tue Sep 26 2023 - 00Z Thu Sep 28 2023 ...Wet weather expected across portions of the Pacific Northwest, Upper Mississippi Valley into the Mid-West and much of Florida into southern Georgia... ...Below average temperatures expected across the Northwest and from Southern New England into the Mid-Atlantic... ...An end to the recent string of record highs over the Southern Plains, but above average temperatures to persist through the Rockies, Southwest, Central to Southern Plains and Middle to Lower Mississippi Valley... A strong area of low pressure across the northeast Pacific is expected to keep the weather pattern cool and wet over the next few days across the Pacific Northwest. The current area of rain stretching from northwest California, northward across western Oregon and western Washington state will be followed by a second area of precipitation moving into the Pacific Northwest on Tuesday night into early Wednesday morning. These periods of rainfall are much needed as much or Oregon and Washington state are experiencing severe to extreme drought conditions. In addition to the rainfall, temperatures will be below average with highs 10 to 20 degrees below average from northern California into much of Oregon, Washington and northern Idaho. Below average temperatures also expected to persist from southern New England, south into the Mid-Atlantic as a nearly stationary area of low pressure off the Mid-Atlantic coast keeps these areas in clouds and occasional showers. A separate slow moving mid to upper level low will also keep wet conditions from portions of the Upper Mississippi Valley into the Mid-West as it moves slowly southeastward over the next few days. The clouds and rainfall across these area will also keep temperatures slightly below average. In contrast to the cooler than average temperature regions, above average temperatures will persist across the Rockies, Southwest, Central to Southern Plains and into the Middle to Lower Mississippi Valley. While temperatures will be as much as 10 degrees above average across these regions, no record highs are expected, bringing an end to the recent string of record highs across portions of the Southern Plains. Wet weather also likely over the next few days across nearly all of Florida into southern Georgia as an upper level low sits across the Gulf of Mexico and pumps above average moisture values northward. These heavy rains may produce isolated areas of flash flooding, especially in urbanized regions. Oravec Graphics available at
