Weather Discussion ( April 24-28 )
Weather is never dull amid the mountains, or so it seems, with chilly conditions on Saturday giving way to coldness into Sunday morning ( April 24 ). While the MIN reached a chilly 38 degrees in Clintwood, amid fog, there was frost in higher mountain valleys.
MIN temperatures dropped below freezing in colder valleys of the High Knob Massif to Burkes Garden corridor, with an official MIN of 31 degrees in Burkes Garden being representative of valleys at around the 3000 foot level.
Amid the trend of this spring, temperatures soared from 38 degrees up to 80 degrees in Clintwood by late Sunday before dropping back ( plunging ) to 42 degrees by Monday AM.
Back to work Monday was simply gorgeous, and warm, but with a rather notable difference in temperatures between upslope locations in the High Knob Massif, Norton-Wise and Sandy Ridge communities on breezy-gusty SW winds verses the downslope locales ( much warmer ) from Pound-Grundy.
Max temperatures on Monday afternoon varied from 60s above 3200 feet in the High Knob Massif to 73 degrees at the 2650 foot level of Nora 4 SSE to 80 degrees at the 1560 foot elevation of Clintwood 1 W.
The overnight hours of Tuesday is featuring a typical nocturnal inversion with 40s in cooler mountain valleys verses upper 50s to low 60s along mid-upper elevation mountain ridges and plateaus ( 47 degrees in Clintwood vs 63 degrees at LNP in Wise at 4:15 AM ).
The focus now shifts to a stormy, much more active weather pattern with a major severe outbreak of thunderstorms and tornadoes across the nation’s heartland today into tonight. A few strong-severe thunderstorms may also develop on a warm frontal boundary and move southeast into the west side of the Appalachians by late today into tonight.
Other showers & thunderstorms, of a more hit-miss nature, may develop amid the warm sector south of the warm front by late in the afternoon into this evening. The most organized storms, with a possible MCS type cluster, will track along & south of the warm front and will bear close watching by tonight for locations from the Cumberland Mountains to the northwest & north.
Downpours could produce locally heavy rainfall amounts between Tuesday Night and Thursday Night, with several rounds of showers and thunderstorms being possible.
Stay tuned to NOAA Weather Radio for any possible watches or warnings that may be needed during the next 24-48 hours.
