Scattered severe wind gusts a few tornadoes sized hail enhanced risk of severe thunderstorms CNY

021556 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1056 AM CDT Fri Jun 02 2023 Valid 021630Z - 031200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS WEST TX... ...SUMMARY... A few tornadoes, destructive baseball to softball sized hail, and scattered severe wind gusts to around 80 mph will be possible across parts of the southern High Plains into this evening. ...Southern High Plains... Large-scale ascent is already underway ahead of a shortwave trough over NM that will slowly shift into west TX through tonight. Stratus is fairly pervasive across most of west TX, outside of the Permian Basin. In this latter area, with mid 60s surface dew points and a pocket of nearly full insolation, convection will likely develop in the next couple hours. With around 8-9 C/km mid-level lapse rates and an elongated nearly straight-line hodograph, splitting discrete supercells are expected with very large to giant hail possible. A couple long-lived supercells may occur as they slowly move southeast along the Lower Pecos Valley through early evening. More widespread thunderstorm activity is expected farther north, initially beginning in southeast NM and then spreading into the South Plains and southern TX Panhandle areas. Relatively larger low-level SRH compared to farther south should support potential for at least a couple tornadoes in addition to significant severe hail, centered on the late afternoon period. Amalgamation of numerous cells should result in upscale growth into an MCS by early evening with a threat for localized significant severe wind gusts. Overall severe threat should wane after sunset into late evening as the MCS spreads deeper into southwest OK through the Big Country. ...Central High Plains to eastern MT... Isolated to scattered thunderstorms will develop along a lee trough later this afternoon in the presence of generally 50s surface dew points. Convection will probably tend to focus near a pair of slow-moving mid-level impulses across eastern CO and eastern MT. For the eastern MT regime in the mid-levels, lapse rates will be weak but compensated by a belt of 25-30 kt southeasterlies. This may be adequate to support transient weak supercell structures. In the eastern CO regime, steep mid-level lapse rates will counter weaknesses in the low to mid-level hodograph. Isolated severe hail and wind will be possible, centered on the late afternoon to early evening. ...New England... Isolated to scattered thunderstorms are expected downstream of a southward-moving shortwave trough approaching from Quebec. Nearly all enhancement to mid/upper flow will be confined to the cool side of a surface cold front pushing south-southwest. 12Z GYX sounding revealed very light winds throughout the troposphere. As such, single-digit effective bulk shear is anticipated across most of the region, with values perhaps into the teens closer to the front. Well-mixed and inverted-v thermodynamic profiles should support locally strong wind gusts in sporadic microbursts during the late afternoon to early evening. ..Grams/Thornton.. 06/02/2023 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z CURRENT UTC TIME: 1619Z (12:19PM), RELOAD THIS PAGE TO UPDAT
