MAG5035 Posted January 23, 2017 Author Share Posted January 23, 2017 Down to 37, and heavy rain right now with big drops. Keeping an eye on it closely for mixing. Link to comment Share on other sites More sharing options...
Voyager Posted January 23, 2017 Share Posted January 23, 2017 While I sit near Hickory NC, it looks like a mixed bag, per radar, in my town of Tamaqua. Reported temp on my weather app is 34 degrees right now. Link to comment Share on other sites More sharing options...

djr5001 Posted January 23, 2017 Share Posted January 23, 2017 Also worth noting that dew point temperatures have been starting to fall across a portion of PA from northeast and spreading southwest with the wind flow - just have a feeling there will be a wintry surprise (even if its just a sleet/snow combo) in some areas with some elevation where current forecasts are for rain with little to no accumulation with a changeover.

MAG5035 Posted January 23, 2017 Author Share Posted January 23, 2017 It appears the turnpike is closed eastbound between Somerset (110) and Bedford (146). The 511 cams near the Allegheny Tunnel (123ish) looks to have heavy snow falling with snowcovered roads. Link to comment Share on other sites More sharing options...
MAG5035 Posted January 23, 2017 Author Share Posted January 23, 2017 Pretty much almost all sleet now, with some wet flakes starting to mix in. Temp down to 35. The transistion is clearly evident on the CC dual pol product as the zone of lower CC values (mixing) is racing northward (down the column) up I-99 toward the CCX radar. Pretty cool to see.

Jmister Posted January 23, 2017 Share Posted January 23, 2017 I'm guessing we have an imminent NWS update coming because they've upped the snowfall in State College from 1-3 to 2-4 Rain before 7pm, then rain and snow between 7pm and 1am, then snow after 1am. Low around 32. Northeast wind 6 to 9 mph. Chance of precipitation is 100%. New snow accumulation of 2 to 4 inches possible. Link to comment Share on other sites More sharing options...

It's probably going to be snowing before 7pm in State College as well, now mostly snow down the road here (not too heavy attm). I expect they'll eventually need the advisory for a tier or two into the central zones, but we need to keep up heavy rates at our lower elevation. Noticed the 12z Euro got it's 6+ zone all the way through the middle of the state into western MD. It's a little late in the game for globals but it did seem to up the QPF. 15 minutes ago, Wmsptwx said: Thinking it'll take solid elevation to see anything notable. NWS not seeing anything to pull trigger on headlines outside of northern tier and mountains. .NEAR TERM /UNTIL 10 PM THIS EVENING/... * Major cyclone to affect the region through tonight * Elevation dependent snow storm likely * Several inches of heavy wet snow not out of the question even throughout the Central Valley areas * Strong easterly LLJ 50-65kt/5-7 sigma...translating to wind gusts of 35 to 45 mph near and to the east of the Susquehanna Mainstem * High probability of at least 1" QPF over much of central PA * Explosive dynamic cooling leads to steep mid level lapse rates and a few instances of thunder snow across the region late today and tonight The deep storm that has been responsible for several rounds of severe storms and deadly tornadoes over Dixie the past several days, is now located near Norfolk, VA and will take a track to the northeast up along or just off the NJ coast tonight. Increasing upper diffluence and mid-level frontogenesis across the Mid Atlantic Region will lead to bands of moderate to briefly heavy precip pushing NWWD, then consolidating on a roughly NE/SW axis near the front range of the Alleghenies from near KELM...to KFIG and KUNV...to KAOO and KIDI late today through at least the first half of tonight as the channel anomalously high PWAT air and low-level easterly winds pivots around the north side of the approaching, negative tilt Upper Low. Multi-model and EFS Vertical Thermal Profiles are very close to supporting various types of precip...in various locations as dynamic cooling lowers temps at all layers just below freezing over the Laurel Highlands first late today, then across central and NEPA where varying thickness of the slightly above freezing layer of marine air off the Atlantic will be found. We maintained the basic timing and configuration of the previously posted Winter Storm Warning and Advisories for NCENT PA, but issued a fresh Winter Weather Advisory for the Laurels for late this afternoon through midnight where 2-4 inches is expected in the valleys there, with higher amounts of 5-6 inches on the ridge tops AOA 2200 FT MSL. 17Z HRRR shows the first batch of moderate to heavy QPF (in the form of Rain to Sleet, with Laurel Highland Wet Snow) lifting gradually north across the CWA between 21-02Z and becoming concentrated across the northern tier counties of PA later tonight. Elevated...slantwise instability coupled with steepening mid/upr lapse rates moving in from the south should lead to some isolated TSSN (or TS some precip type) through at least early tonight. A second surge of mid/upper level energy pushes NWWD over much of central and eastern PA after midnight and lingers through daybreak in the form of an "elongating" area of "Wraparound" snow/sleet. The main change for later this evening may be the need to extend the Winter Weather Advisory to fill in some of the Central Susq Valley and Central Mtn zones for up to several inches of Wet Snow. Temperatures in most locations of Central and Northern PA will be nearly steady or slowly falling from the mid and upper 30s late today, The rain will mix with, then change to sleet and wet snow during the mid to late afternoon across the higher terrain of central and western PA where temps will be between 32 and 34F. A gradual changeover to sleet and wet snow of varying intensity will occur throughout the central valleys and northern mountains between 5 and 7 pm. PTYPE will be mainly rain across the Lower Susq Valley through the first half of tonight, then a rain/wet snow mix with up to a slushy 1 to 2 inches on the ridges around and to the north of the Greater Harrisburg Area.
