Storms completely split me here in Millersville, not a single drop. Heard some thunder though

Excited for this cold front to come through that's in north central PA right now. NW flow and low dew points the next two days. Yes please

Severe watch up

Did you make these graphs yourself? If so, did you use Python, Excel, or something else? Nice work regardless, and interesting to look at

Looks like Low level lapse rates will slowly improve through the day as the residual cloud cover from the east continues to burn off. That's almost a given, the surface heating will almost always bump LLLRs to >7C/km range. MLLRs are forecast by the RAP to improve throughout the day as well, into the evening. In fact, the SCP is expected to increase from the already high value its at right now, likely aided by the increased lapse rates. Same with helicity values.... basically what I'm getting at is things are conducive for tornados later. Whether or not we can get any is of course the big question. With the cold front approaching from the west, only into the Indiana region, I think western areas will see the greatest area/influence of enhanced frontal lifting so hence why much of the CAMs keep convection further to the west. We'll see though, I'll be keeping an eye out. It's been active here in Lanco recently, that's for sure

Bulk shear values are actually pretty impressive compared to previous days across PA. I picked the Harrisburg area as a pinpoint for SPC tornado climatology, the red bars represent current values. I'm not expecting any tors per-say, but low LCLs, high bulk shear, high supercell composite values, high CAPE, high STP values means it's certainly not out of the question. Problem always seems to be mid-level lapse rates around here, they are on the meager side if you're looking for something to nitpick and enjoy severe weather.

It's gotta be like 5 of the last 7 days the Berks/Lehigh Valley have been under a Severe Thunderstorm Watch. Can't remember the last time we've been under such a consecutive streak of possible severe days.

The one warning is for 80mph winds geez

Tornado risk for much of west central PA today

That storm in Bergen/Rockland counties is warned for 2 inch hail

Heading backpacking tomorrow-Sunday. Don't need Elsa to ruin things and rain on me. Keeping things I-95 SE is fine with me.

High probability of severe wind in the new watch Tornadoes Probability of 2 or more tornadoes Low (10%) Probability of 1 or more strong (EF2-EF5) tornadoes Low (5%) Wind Probability of 10 or more severe wind events High (70%) Probability of 1 or more wind events > 65 knots Low (10%) Hail Probability of 10 or more severe hail events Low (20%) Probability of 1 or more hailstones > 2 inches Low (<5%) Combined Severe Hail/Wind Probability of 6 or more combined severe hail/wind events High (90%)

Lots of low level 0-1km veering on the 3k NAM for NYC tomorrow afternoon. Limited CAPE and surface heating though compared to recent events.

Pressure down to 998 at 5pm, still 70mph TS

DISCUSSION...Isolated to widely scattered strong/severe storms have developed over western NY as of 16z within an air mass characterized by moderate MLCAPE and generally weak (at or below 25 kts) effective shear values. Despite the lack of large-scale forcing, additional thunderstorm development is anticipated over central portions of NY and in the vicinity of a surface trough from the Delaware Valley into southern New England as remaining weak MLCIN is removed through daytime heating, with multiple multicell clusters moving generally east/southeast this afternoon. A belt of enhanced westerly flow averaging 35-40 kts will result in a risk for damaging downburst winds with the stronger storms and clusters. Generally weak deep-layer shear and poor mid-level lapse rates will temper the hail risk, however a few stronger updrafts may be capable of marginally severe hail. Given the expected development, one or more Severe Thunderstorm Watches is expected by early afternoon.

Euro is a scraper, gets it down to 988 off the Cape

11pm update: 65mph winds and 1004mb pressure

Also, marginal risk of storms today for wind and hail ...Northeast States... A seasonably cold mid-level low over Lake Erie should drift east across northern PA through tonight. While pervasive cloud coverage this morning will slow boundary-layer heating, breaks in the clouds should support weak buoyancy this afternoon from central PA into southern NY and NJ. Steepening mid-level lapse rates and the presence of an elongated hodograph owing to strong mid to upper-level speed shear should support potential for hail growth as isolated to scattered thunderstorms develop to the east-southeast of the low. Isolated marginally severe hail will likely be the primary threat, in addition to possible tree damage from locally gusty winds.
