DISCUSSION

Issued at 232 AM CST Sun Feb 1 2026

Today through early next weekend (Saturday)...

Today: Morning water vapor/RAP analysis indicate upper closed low/deepening cyclogenesis over the Atlantic seaboard and Carolinas. This is leading to a powerful winter storm in those areas. Further west, the Gulf Coast states remain in northerly flow aloft, while situated between the trough over the eastern seaboard while deepening ridge of the Desert Southwest to Baja Peninsula. At the surface, 1035mb surface high just to the west will ooze southward through the day. There is a slight gradient in the east, so at most light northerly surface winds are expected through the day. Temperatures this morning are bottoming out colder in the teens, but lighter winds limit any wind chill to the east. Ongoing HWO and cold headlines remain on track through midday. Some frost is likely for areas that don't have too much clouds. We finally warm above freezing around noon, while the Delta could remain below through early afternoon. Highs will be seasonably cool (35F to 40F in the Delta while up to 45F to the southeast), with one last subfreezing night well into low to mid 20s Monday morning.

Next week into early next weekend (Saturday): As arctic cold pattern shifts eastward, shortwave ridging will build out of the Plains into the southeast by Tuesday. Mean northwest flow will gradually shift more southwesterly flow and moist ascent. Precipitable water (PWs) will climb to in excess of one inch. Combined with moist ascent, some rain chances (cannot rule out a rumble of thunder) are on tap Tuesday afternoon through midday Wednesday before seasonably cool and dry pattern through Thursday. 1025mb surface high will drift through Thursday before another reinforcing dry front moves through and another 1030-1035mb surface high sags southeast into the Mid-West to OH Valley by late Saturday. Temperatures will rebound briefly Friday before falling back to seasonable norms next weekend. /DC/
