Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 254 AM EST Tue Mar 02 2021 Valid 12Z Tue Mar 02 2021 - 12Z Thu Mar 04 2021 ...Showers and thunderstorms are likely across the Southeast through tonight, with isolated flooding possible... ...Gusty winds and cold wind chills are expected in the Northeast today, along with snow in the interior through Wednesday... A surface low pressure system is expected to move eastward along the Gulf Coast today and tonight, and as Gulf moisture streams into the region, rain and thunderstorms are forecast across the Gulf Coast states to the north of the low. Rain amounts of 1 to locally 3 inches are expected over southern Alabama, Georgia, and South Carolina as well as northern Florida through early Wednesday. A Marginal Risk of excessive rainfall is in place for these areas, indicating isolated flash floods are possible. Rain should clear out by Wednesday afternoon as the low makes its way into the Atlantic. The southeastern U.S. can also expect cooler than normal temperatures with highs in the 40s and 50s today, moderating closer to normal (but still 5 to 10 degrees below) on Wednesday. In the Northeast, strong winds are forecast today due to a tight pressure gradient from a deep surface low in southeastern Canada. Thus High Wind Warnings are scattered across the region, along with widespread Wind Advisories from the northern Mid-Atlantic into New England. The gusty winds combined with cold temperatures have led to the issuance of Wind Chill Warnings and Advisories this morning for portions of the Northeast. Additionally, rounds of snow showers are possible for the Great Lakes region into the interior Northeast over the next couple of days. Snow amounts should be relatively light, except for in the Adirondacks where 6+ inches are possible in higher elevations. Meanwhile, dry and relatively warm conditions are forecast in the north-central U.S., where high temperatures will be 15 to 25 degrees above normal through the next several days. Elsewhere, as an upper-level low and frontal system approach the southwestern states on Wednesday, rain showers are possible for Southern California into the Desert Southwest. As precipitation spreads farther inland into the Four Corners states Wednesday night, snow is expected for higher elevations in particular, with a few inches possible in the peaks of the Mogollon Rim, Wasatch, and San Juan Mountains through Thursday morning.
