A significant winter storm continues to impact much of the West with heavy mountain snow and widespread damaging winds, including dangerous, blizzard conditions in the Sierra Nevada. In the Central and Southern High Plains, an expansive area of warm, dry, and windy conditions is leading to a large area of elevated to high-end critical fire-weather conditions. Toggle navigation.

Includes ability to download reports and associated metadata in csv format. Spring maximum temperatures ranging upwards to degrees above normal will spread from the Midwest toward the Northeast to offer potential for some record values. This will aid in copious amounts of rainfall over the span of hrs, but rates will be lacking as probability of exceeding anything over 0. Norman, OK U. Featured News. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Press enter or select the go button to submit request. Disclaimer Information Quality Help Glossary. Nevertheless a couple tornadoes are possible, especially if greater moisture than forecast can make it this far north. By the end of Day 3, the sweeping front will have progressed through the East Coast and with it, a rapidly colder airmass takes over. This will cause increasingly more significant impacts to travel as snow spreads into the lowlands and valleys through much of the West, with significant travel problems likely at most of the area mountain passes from the Cascades through the Central Rockies. The strong cold front will continue progressing through the region, reaching the Northern Rockies on Monday and the Central Rockies on Tuesday. Plots of GEFS probabilistic forecast of precipitation, temperature, and sea-level pressure exceeding various thresholds.

Lowering snow levels will also produce some accumulations onto the valley floors. Weather Prediction Center. Prototype Specialized Excessive Rainfall Maps. Although the antecedent airmass is marginally cold enough for heavy snow, the isentropic ascent atop the front combined with the rapidly cooling airmass indicates much of the precip will be anafrontal, which will overlap with the colder air, a deepening DGZ, and periodic impressive fgen to drive heavy snow rates. However, forecast dewpoints are only expected to reach into the 50s to near 60 F. The question that still needs to be solved is where that boundary will lie. Press enter or select the go button to submit request. A robust mid-level shortwave will propagate southeast out of the Pacific Northwest on Tuesday with increasing difluent flow ahead of the mean trough that will help initiate a round of convection within the confines of the Mid-Mississippi and Ohio Valley's. Focused meridional flow ahead of the mean longwave trough will advect deeper moisture and associated theta-E's poleward with a tongue of elevated instability building within the areal theta-E advection regime. In addition, much colder air will move in behind the strong cold front. This will continue to advance eastward and the focus shifts into the Appalachian front and terrain-centric areas in the Mid-Atlantic and Ohio Valley as we roll into D3. Nevertheless a couple tornadoes are possible, especially if greater moisture than forecast can make it this far north. A strong winter storm and cold front will move across the Pacific Northwest to the Central Rockies by Tuesday evening.
