NWS Mount Holly Briefing Package - 430 PM Friday

2015-02-20 17:09:29 emccmp

http://www.erh.noaa.gov/phi/briefing/packages/current_briefing.pdf

Emergency Managers and other key partners,

Attached is a briefing package for the winter weather event expected this weekend. The Executive Summary is as follows:
• Very cold temperatures are expected again tonight, with lows ranging from 5 degrees below zero in the Poconos and northwest New Jersey to around 5 degrees elsewhere. However, there won’t be much wind, so it won’t feel quite as bad as last night.
• Then another storm will approach from the west on Saturday. Very cold temperatures in the morning will slowly warm through the day, but precipitation is expected to begin as snow Saturday afternoon across our entire County Warning Area (CWA). Then, as warmer air moves north, snow will change briefly to sleet, then rain, from south to north. By evening, rain or rain/snow/sleet mixture is expected in Philadelphia and points south, but with so much entrenched cold air, the transition will take longer further north. For instance, the Lehigh Valley and central New Jersey may not transition to rain until Sunday morning. Please see attached maps for snowfall forecasts.
• Where rain makes contact with very cold surfaces, ice buildup could occur. However, right now we don’t see this as a widespread problem.
• Precipitation will end from west to east on Sunday as another arctic cold front moves in, bringing below normal temperatures to the region for the beginning of the new week.
• Northwest winds will bring low-water conditions on the ocean front, as well as both the Chesapeake and Delaware Bays (including tidal Delaware River), at the time of low tide tonight, and perhaps again at the time of low tide on Saturday.

CONTINUED BITTER COLD FOLLOWED BY SNOW & RAIN FEB 19-22

2015-02-19 17:59:52 emccmp

Weather briefing WFO PHI – 2015-02-19 430 PM (2)

Bitter cold tonight through Friday night will be followed by another storm Saturday into Sunday. Temperatures on Saturday are expected to rise
through the day and night, changing snow to rain, so accumulations will be tempered. A briefing package is attached. The Executive Summary is
as follows:

• Record breaking cold will continue over the area into Saturday. Tonight and Friday will be the coldest, with overnight lows 10 to 15 degrees below zero in the far north, and only in the single digits in the south. Winds in the 15 to 25 mph range will drop Wind Chill values down to the minus 25 to minus 35 degree range in the southern Poconos and northwest New Jersey, and in the minus 10 to minus 25 degree range in most other places. Wind Chill Warnings and Advisories have been posted. Friday night will be cold too, but not quite so bitter, and with less winds, it won’t feel quite so bad.
• Another storm is expected to affect the region Saturday into Sunday. Temperatures will be warming on Saturday, but not before snow starts from west to east late Saturday morning or early afternoon. Then precipitation will change from snow to rain from south to north later Saturday afternoon and evening. By Saturday night, precipitation should be all rain south and east of the I-95 corridor. This transition will take longer north and west of Philadelphia, but by Sunday morning, all rain is expected in these areas too. The transition to all rain may take until Sunday morning in the southern Poconos and northwest New Jersey. During the transition from snow to rain, there could be some sleet and a brief period of freezing rain, but ice is not expected to be a major problem with this event.

ANOTHER BITTER COLD OUT BREAK

2015-02-18 18:26:10 emccmp

Weather briefing WFO PHI – 2015-02-18 Snow is possible tonight with a frontal system representing the leading edge of much colder air moving in
for the remainder of the week. An inch or two is possible north and west of Philadelphia by morning, with an coating to an inch
possible in the south. The big story for the next several days will be the bitter cold. Think this past Sunday and Monday,
but colder. We are looking at actual air temperatures not seen for decades Thursday night and again Friday night.
Strong northwest winds Thursday night into Friday morning will bring wind chill values down to the -20 to -35 degree range.
It’s going to be bitter cold. Take all necessary precautions.

A briefing package is attached. The Executive Summary is as follows:
ANOTHER BITTER COLD OUTBREAK
• Temperatures tonight (Wednesday night) will be cold with lows in the single digits in the north to the low to mid teens south.
• Bitter record breaking cold will overspread the area Thursday through Friday night with overnight lows sinking to NEGATIVE single digits in many areas. Thursday night into early Friday morning is expected to be the coldest when actual air temperatures could dip to 15 degrees below zero in the southern Poconos and northwest New Jersey. Northwest winds in the 20 to 30 MPH range (and stronger gusts) at the same time will combine with these cold temperatures to create dangerous wind chill values in the minus 20 to minus 35 range. Use this past Sunday and Monday as an example…only colder. Cold weather is expected to then continue into Saturday, but the wind won’t be so strong.
• Another storm may affect the region Sunday into Monday. With warmer air moving in with this system, a wintry mix of snow…sleet…freezing rain…and plain rain are possible, depending on location. Stay tuned!
