MID-ATLANTIC AND SOUTHERN NEW ENGLAND — With roughly 48 hours until the expected start of a significant winter storm, forecast guidance has narrowed into two primary scenarios — and both would bring impactful snow to parts of the Mid-Atlantic and Southern New England. The key question now is not whether someone sees heavy snow, but…
NORTHEAST UNITED STATES — A notable shift in the upper-level pattern is increasing the potential for a more significant winter storm across the Northeast late this weekend. Updated ensemble guidance shows a stronger negative North Atlantic Oscillation (-NAO) block and a repositioned western ridge — a setup that is often favorable for impactful snow along…
EASTERN UNITED STATES — A powerful storm system now crossing the Southwest is forecast to intensify as it reaches the East Coast Sunday, with forecasters branding the setup “Blizzardsaurus” due to its potential size and impact. The system is expected to strengthen Sunday into Monday, bringing a high probability of a major snowstorm to parts…
WASHINGTON, D.C. — With just two days to go before a potential Northeast winter storm, forecast models remain sharply divided — and the difference could mean the contrast between a major snow event and a near-miss for millions along the I-95 corridor. New data from the U.S. GFS model continues to depict a significant snowstorm…
MID-SOUTH AND OHIO VALLEY — A significant severe weather event unfolded across portions of the Mid-South and Ohio Valley on February 19, and early verification suggests the Storm Prediction Center’s 10% tornado probability area was well placed. While at least seven tornadoes have been logged so far, forecasters say a couple of additional tornadoes remain…
NORTHEASTERN UNITED STATES — A winter storm is looking increasingly likely to impact the Northeast this weekend, with the potential for widespread accumulating snow from Sunday into Monday.

WASHINGTON, D.C. TO BOSTON — Whether the I-95 corridor sees a blockbuster blizzard or a complete miss may hinge on a feature thousands of miles away — a ridge building over the Pacific Northwest near Boise, Idaho. Meteorologists are closely watching the Pacific-North American (PNA) pattern, as a strong ridge over the Northwest could set…
PENNSYLVANIA — Forecast confidence remains exceptionally low ahead of the approaching Sunday snowstorm, as major global models continue to produce dramatically different snowfall outcomes — especially for Philadelphia and surrounding parts of the Mid-Atlantic and Northeast. Morning model updates show projected totals for Philadelphia ranging from as much as 24 inches… to 6 inches… to…
FLORIDA AND THE GULF COAST — Lingering La Niña conditions continue to suppress rainfall across the Deep South, and new extended model guidance shows significantly below-normal precipitation persisting through late March — a trend that could sharply elevate wildfire risk across Florida and Gulf Coast states. The latest 35-day precipitation anomaly outlook highlights widespread negative…
INDIANA — The Storm Prediction Center (SPC) has upgraded portions of central and southern Illinois and southwest Indiana to an Enhanced Risk (Level 3 of 5) for severe weather today, highlighting an increased tornado threat — including the potential for strong tornadoes (EF2 or higher). The latest outlook shows a 10% probability of a significant…
