ACUS01 KWNS 251959 SWODY1 SPC AC 251957 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0257 PM CDT Fri Jul 25 2025 Valid 252000Z - 261200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE NORTHEAST AND MID ATLANTIC...PARTS OF THE MID MISSOURI VALLEY...AND ACROSS THE NORTHERN PLAINS.... ...SUMMARY... Scattered strong to severe thunderstorms remain capable of damaging wind gusts across parts of New England and the northern Mid-Atlantic States this afternoon/evening. Severe storms will also be possible across much of North Dakota as well as eastern Kansas into western Missouri. ...20z Update Northeast... Scattered to numerous thunderstorms ongoing ahead of a weak cold front across the Northeast and northern Mid Atlantic states will continue to pose a risk for isolated damaging gusts through this evening. The main focus for storm development/intensification along the front will continue to shift southeastward this afternoon. Trimming was done to the MRGL area mainly where the wind shift has already moved offshore. Otherwise the SLGT risk area was adjusted to better match the higher storm coverage and threat for damaging gusts. ...KS/MO... To the west, scattered severe storms should continue to develop/intensify this afternoon ahead of an MCV/shortwave trough across parts of KS and MO. Very moist surface conditions are present with mid 70s F dewpoints contributing to moderate destabilization despite weak low and mid-level lapse rates. Enhanced mid-level wind fields observed by area VADs should support a few stronger storms including supercells capable of damaging gusts and possibly brief tornadoes this afternoon and evening. ...Great Basin... Isolated to scattered high-based thunderstorms remain likely across northern CA and western NV this evening. Steep low-level lapse rates will favor dry microburst potential with these storms or any more persistent clusters of storms able to evolve. Have adjusted the MRGL risk slightly west to better capture storms developing near the higher terrain. Otherwise, see the previous discussion for additional information. ..Lyons.. 07/25/2025 .PREV DISCUSSION... /ISSUED 1142 AM CDT Fri Jul 25 2025/ ...Northeast/Mid-Atlantic States... Midday vapor imagery shows a fast-moving shortwave trough progressing eastward into Quebec. An associated cold front will move south-southeastward across New England this afternoon. Relatively hot/humid conditions ahead of the front will lead to widely scattered afternoon thunderstorms across southern New England and eastern portions of New York/Pennsylvania. These storms will track southeastward toward the coast through the early evening with damaging winds possible. ...Northern Plains including North Dakota... An upper ridge remains centered over the central Plains, with a weak southern-stream trough currently moving across Utah into Wyoming. Weak lift and increased mid-level moisture ahead of the system will aid in the development of scattered thunderstorms by late afternoon across parts of eastern Montana and northeast Wyoming. Thermodynamic parameters are favorable for large hail in the stronger cells. It seems that these storms will tend to persist east-northeastward this evening and pose a risk of hail and locally damaging winds across North Dakota. ...Eastern Kansas/western Missouri... Regional WSR-88D VWP data continues to sample modestly enhanced low/mid-tropospheric flow in relation to a slow-moving MCV, notable from KEAX where 35-40 kt west-southwesterly flow persists between 3-5 km AGL. With a very moist air mass in place (low to middle 70s F surface dewpoints), intensifying storms could include supercells given some likely persistence of the enhanced flow field. Especially with a convectively reinforced surface boundary, a semi-focused corridor of damaging winds and brief tornado potential could evolve this afternoon into early evening. ...Northern California/western Nevada... Aside from the dry thunderstorm potential (see Fire Weather Day 1 Outlook), sufficient moisture/buoyancy may exist on the eastern and northern periphery of the slow-moving upper low, where mid-level temperatures (-12C at 500mb) are semi-cool, to allow for some hail and/or convectively enhanced wind gusts this afternoon through around sunset. $$ |
