Area Forecast Discussion National Weather Service State College PA 242 PM EST Sun Dec 15 2019

SYNOPSIS. The next weather system will move into southern portions of the area overnight and slowly spread north on Monday. This system will bring a mixed bag of winter precipitation with it until temperatures warm up above freezing later on Monday. Please use caution when travailing across southern Pennsylvania late tonight and Monday. An upper level trough will swing through the northeast US during the middle of the week, then high pressure will likely build in to end the week. Cold temperatures will begin to moderate by late in the work week.

NEAR TERM /THROUGH TONIGHT/. LES showers winding down across NW this afternoon. Some brief clearing ahead of next weather system will allow for several hours of radiational cooling. This weather system will bring wintry precipitation across the southern zones late tonight and Monday morning. Elsewhere look for increasing clouds late.

SHORT TERM /MONDAY THROUGH TUESDAY/. Messy start to the southern zones with approaching low pressure system. After initially starting as snow, as has been the case most of the last month, mild air will quickly work its way in just aloft to change the phase of the precipitation to sleet and ultimately freezing rain and then rain. With the heating of the day and milder air working in, temperatures will rise above freezing and the wintry precipitation threat will end in the afternoon, leaving the bulk of the precipitation with this system as plain rain. Will cover this with a winter weather advisory for our southern zones. Further north, the storm system will bring light snow or flurries with it, but it will be working against fairly dry low layers and rates will be light throughout much of the event. Low level warming will also turn any snow into a light wintry mix with lower qpf totals as you move north.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. Northern snow/southern rain should taper off Tuesday evening, as surface wave exits the Mid Atlantic coast. The 00Z NAEFS and ECENS both support a period of below average temperatures during mid week, as an anomalous upper trough swings through the northeast conus. The flow off of the Grt Lks briefly appears favorable for lake effect snow showers across northwest Pa Wednesday, then the arrival of surface high should result in a period of fair weather through the balance of the work week.

Model spread and forecast uncertainty ramp up toward next weekend. Much of the guidance has a digging trough approaching from the midwest, so anticipate moderating temperatures ahead of this feature and a possible need to introduce a chance of rain/snow showers by Saturday.

AVIATION /20Z SUNDAY THROUGH FRIDAY/. Snow showers across the nw continue to produce IFR conds at BFD and MFVR at KST and KAOO with slow improvement into the evening expected. VFR should continue elsewhere. Westerly winds will continue to be brisk, and strongest over the western half. Sustained speeds around 15 mph will be common, with gusts to 25-35 mph over the western higher terrain, closer to 25 mph gusts over the east. Winds subside this evening as just about everywhere remains VFR (the NW mountains may hold on to MVFR cigs).

Next next system slides in from the SW late tonight into Monday, spreading widespread restrictions back into the region, with MVFR-IFR ceilings and vsbys in snow. As warmer air changes precip through a wintry mix and then to plain rain over the southern half later Monday into Mon night, vsbys will improve but widespread ceiling restrictions will remain.

Outlook.

Mon . PM low cigs/wintry mix possible.

Tue . Low cigs NW, improving conditions elsewhere.

Wed . Restrictions likely north/west with snow showers.

Thu and Fri . No restrictions expected.

CTP WATCHES/WARNINGS/ADVISORIES. Winter Weather Advisory from 2 AM to 4 PM EST Monday for PAZ033>036-063>066.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
