WEATHER BLOG: Warm Air Moves Into The Region
A storm system moving over Canada will be pulling warm air into the region today, as has been discussed now for many days in advance. Temperatures are expected to absolutely soar today. A more beautiful day is hard to come by in February.
Tomorrow temperatures will remain mild, however a weak surface low riding a weak upper disturbance will pass over the southern portions of the I-95 corridor and bring some afternoon rain as far north as Allentown, Trenton, and Atlantic City. So for the weekend in general, Saturday will be the nicer day of the weekend.
The afternoon rain on Sunday afternoon will continue into Sunday night, however by Monday morning it will be back dry again.
High pressure will already be moving back into the region on Monday, clearing skies out. The source of that high however is polar in nature and brings cold air back behind the system. Temperatures will not be as warm on Monday as before the disturbance, but they will still be above normal for the time of year.
After that is when things get complicated and forecast confidence drops dramatically. An approaching upper trough will sling multiple disturbances towards the east coast. The European maintains a storm will be moving up the Appalachians while the latest GFS runs say the first pulse will go straight out to Sea. The thought here is that based on how far west the trough is along with the upper ridge location out west, that the system should act as the European would suggest, so the forecast has leaned in that direction, meaning a wet day for most of the I-95 on Tuesday into Tuesday night with snow across more inland areas.
Part two of the system follows close on the heels of part one, moving up the east and bringing similar conditions as part one, but perhaps to a greater extent as this low will be more fueled by the upper trough than the first. Luckily, again, it looks like the low track is west of the I-95 corridor and that means we should be looking at rain instead of wintry precipitation.
