Central PA Spring 2022


Recommended Posts

CTP seems confident in storms later today.

“A well-defined cold front will move across CPA this afternoon and evening accompanied by numerous downpours and a few strong to locally severe t-storms. SPC pulled the SLGT risk farther southwest into northeast PA with the 5/21 day 2 update - and made little to no changes in carrying the SLGT over to day 1 (today). The MRGL risk area expanded to include the majority of the CWA outside of the NW Alleghenies. The convective environment will be driven by relatively strong boundary layer heating ahead of the cold front. Fcst maxTs in the 80-90F range (+10-20F above climo) combined with 60-65F dewpoints will support 1-2k J/kg SBCAPE across the eastern half of the CWA. While the best deep shear values (>30kts over the NW mtns) do not overlap with the more robust instability, it should be sufficient to generate some organized multicell clusters. These storms will be capable of producing strong to locally damaging winds as the primary threat given 0-3km lapse rates around 8.0 C/km.”
