Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 208 PM EDT Tue Oct 22 2024 Valid 00Z Wed Oct 23 2024 - 00Z Fri Oct 25 2024 ...Remarkably quiescent pattern continues across much of the Continental United States.... ...Light rain showers across Upper Midwest/Upper Great Lakes today... ...Snow/rain showers crossing Oregon, Idaho toward Yellowstone/Tetons... ...Well above-average temperatures continue over the Central and Eastern U.S... A progressive mid-level trof will continue to rapidly advance across Southern Canada and clip the northern tier states through the Great Lakes Wednesday. The associated cold front will bring some light rain showers across these areas, but slowly dry out as it crosses Southeast Canada and the Northeast by Thursday. Warm air along/ahead of the front will once again promote well above normal temperatures across New England today with some locales potentially reaching record today and Wednesday before returning to normal, or slightly below normal the day after the passage. The mid-section of the U.S. will once again see larger scale ridging allowing temperatures to rise 15-20 degrees above normal into Wednesday/Thursday with some locations in the Southern Plains pushing daily records as well into the low 90s. So not dangerous heat, but clearly atypical. A weak upper-level upper level low will advance into the Pacific Northwest by Wednesday into Thursday. This system will be below average in moisture transport as it quickly moves through the terrain of Oregon, Idaho into southwest Montana/northwest Wyoming producing snow showers and maybe light rain to the lower elevations.
