A very tricky forecast during the next 24 hours with
borderline temperature profiles in the month of March. Some areas may very well
overachieve with snow, sleet, and ice accumulations while other areas may
underachieve. My thought is to best handle this forecast by separating our region....
Dover and Cape May:
Light rain breaks out late tonight and early on Monday
Morning. The light rain may mix with or change to wet snow as temperatures
could drop back a bit closer to daybreak. Then as the sun rises, warmer air will
be advecting down into the lower levels and the sun angle will work its magic.
Snow will changeover to sleet and rain…followed by all rain. A coating cannot
be ruled out if it changes to all wet snow overnight. It may also be foggy in this area on Monday.
Mount Holly, Philadelphia, and Royersford:
Snow and sleet develops by the mid-morning hours. A transition
to rain is expected throughout the afternoon hours. Most areas should observe
plain rain by evening. A coating of snow and sleet is possible which will get
washed away if it occurs. Royersford and Trenton will likely be the last communities in this area to see a change to rain. The higher terrain of Bucks, Mercer, and Montgomery Counties could see a brief period of freezing rain as well. Some patchy fog is possible here as well.
Allentown, Lancaster, and Kutztown:
Snow develops by mid-morning and early afternoon. Then snow
and sleet, followed by freezing rain in the afternoon. A gradual transition to
plain rain will occur throughout the late afternoon and evening hours. There is still some question as to how fast the transition from ice to rain will occur.
Mount Pocono:
Snow with moderate accumulations possible. A changeover to
sleet or at least a snow and sleet mix will likely occur, followed by freezing
rain. It is possible plain rain never occurs here. It is also possible to have
more snow vs. ice here when it is all said and done. Either way…icy and nasty
here.
Otherwise…steady rain and other precipitation types end on
Tuesday Morning and it becomes windy for the remainder of Tuesday into
Wednesday. A few lingering flurries and snow showers are possible Tuesday Night
into Wednesday. However, some breaks in the clouds should develop.
The rest of the extended forecast looks to be brighter, but cool.
