SYNOPSIS. A warm front will lift through the region Monday as an area of low pressure tracks through the Great Lakes. A cold front associated with that low will then approach and cross the region Tuesday. A wave of low pressure tracking along the front will likely affect the mid-Atlantic Tuesday night into Wednesday. Strong high pressure will build in Thursday and into Friday. Another low pressure system may approach the region next weekend.
NEAR TERM /TONIGHT/.
A pleasant and seasonable afternoon will begin to go downhill tonight as high clouds continue to thicken over the region. Low pressure to our west will continue to wrap up, as a warm front lifts north across the area this evening. Highs in the 40s will drop into the 30s tonight, though not nearly as cold as last night as clouds and precipitation move into the region. Light rain and drizzle will begin to overspread the region from south to north after midnight, becoming a steady rain by daybreak. Winds will remain light tonight out of the south.
SHORT TERM /MONDAY AND MONDAY NIGHT/.
Things are not shaping up to be the best weather day Monday as low pressure to our west moves closer toward the mid-Atlantic and southerly flow ahead of the system draws moister air into the region. An initial vorticity impulse along the warm front will lead to an initial round of moderate rainfall across the region through the morning hours, especially from I-95 and points east. Conditions may turn a little more showery into the afternoon before a broader area of steady rain moves eastward from central Pennsylvania. At this point, all rain is forecast for the initial portion of this system. The one uplifting aspect is that the highs will trend much warmer tomorrow, reaching into the 50s and 60s across the region (upper 40s across the Poconos). Southerly winds will also begin to trend upwards with gusts from 20-25 mph possible by the evening and into the overnight hours. Total rainfall through this period is expected to near an inch, but given the extended duration, this is not expected to result in any more than localized nuisance flooding.
LONG TERM /TUESDAY THROUGH SUNDAY/.
Tuesday . As mentioned by the previous shift, we should start the day in the warm sector. However, some guidance trended faster with the front (it may now cross our region mid day, and be off shore as early as mid afternoon), which brings uncertainty into how long we will be in the dry slot on Tuesday morning. However, I am always a bit cautious of a front crossing during the middle of the day when the mid and upper level trough lags so far behind the front at the surface. Therefore, I made few changes to the temperatures and PoPs during the day on Tuesday. Even if the front does arrive by mid day, expect any precipitation (even late Tuesday afternoon) to be all rain.
Tuesday night and Wednesday . Still considerable uncertainty through this period. The front should progress further off shore, but the mid and upper level trough digs in closer to the region, so most guidance depicts precipitation continuing overnight and through much of the day on Wednesday. Without significant cyclogensis just off shore, it would be difficult to get that much precipitation behind the front in this kind of pattern as we should have persistent dry air advection behind the front. If we do have precipitation into Wednesday morning thanks to significant cold air advection we should see precipitation change over to snow mostly north and west of the fall line, and a rain/snow mix along the coastal plains. As mentioned by the previous shift, even if it does happen, it will likely be little more than a nuisance snow, with the possible exception of northwest NJ and the southern Poconos which could see a few inches of accumulation. Though snow totals did increase a bit, this is not the result of major changes in the forecast, rather, the forecast is now incorporating snow amounts during the day Wednesday in addition to Tuesday night.
Thursday . Dry and cold as strong (~1040 mb) high pressure builds in from the west. Generally expect highs to only top out in the low to mid 30s based on 925mb (approximately the top of the mixed layer) temps of -6 to -9C. Given the dry airmass and light winds near the center of the high left Thursday's lows on the lower end of guidance (ranging from low teens up north to the mid 20s over Delmarva, with teens possible in the colder spots of southern/central NJ as well).
Friday . The high will shift to our northeast on Friday, with a warmer and moister east-southeast flow developing over the area. Generally expect dry weather, although the Canadian attempts to bring a southern-stream coastal low through the area in the afternoon, while the GFS attempts to initiate some overunning precipitation Friday afternoon. Given that it will likely take some time for the lower-lvls to moisten suspect that initiating precipitation Friday afternoon is a bit too fast so generally went Slight Chc PoPs. Highs will run about 10 degrees warmer than Thursday with greater warming felt near the coast due to the onshore flow.
Friday night into Saturday . Likely will see rain during this period, however the nature/forcing for this precipitation is currently unclear. The GFS keeps the primary sfc. low inland, and brings it through the Great Lakes late Saturday, while the EC indicates the coastal low will become the primary low and brings it through our area on Saturday (the Canadian depicts this low passing Friday night). Consequently whether we get an warm advective/shortwave driven precipitation event (GFS) or a low- lvl confluence /synoptic-lift driven precipitation event (EC) is unknown. Regardless we should be fairly warm on Saturday with highs generally in the 50s.
Saturday night/Sunday . Given model uncertainties from previous period, the forecast in this period is naturally uncertain. That being said the current guidance suite puts us post-frontal by Sunday with some drying and cooling (although the postfrontal airmass does not seem particularly cold) indicated in the forecast.
AVIATION /20Z SUNDAY THROUGH FRIDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Rest of today . VFR ceilings will continue through the evening as high clouds overspread the region and continue to fill in through sunset. South-southeasterly winds from 5 to 10 knots with a few occasional gusts to 15 knots possible. Winds may also turn south- southwesterly for a short time through 23Z. High confidence.
Sunday night and Monday . VFR early into the nighttime hours, with ceilings lowering to MVFR levels after 05-06Z from south to north. Rain and drizzle to move into the region shortly after, turning into a steady rain by sunrise/12Z. Light and variable wind will turn south-southeasterly by daybreak to 5 knots. Moderate confidence.
Monday and Monday night . MVFR with periods of IFR conditions possible with a mostly steady moderate rain all day. A few breaks are possible with conditions turning more showery into the late afternoon and evening. Southerly winds from 10 to 15 knots and gusts from 20 to 30 knots possible will turn more southwesterly into Monday night. Moderate confidence.
Outlook .
Tuesday and Tuesday night . There may be a brief period of VFR conditions Tuesday morning, but mostly MVFR or even IFR conditions are likely Tuesday afternoon and night. Southwesterly winds abruptly shifting to northwesterly Tuesday afternoon 10 to 15 kt with some gusts to 20 kt especially Tuesday afternoon. Moderate confidence.
Wednesday . The day will likely start with widespread MVFR or even IFR conditions, but by afternoon, conditions should be gradually improving to VFR. Westerly winds near 10 kt. Moderate confidence.
Wednesday night-Thursday . VFR. Light northwest winds becoming northerly on Thursday. High Confidence.
Thursday night-Friday . Generally VFR. Light northeasterly winds Thursday night veering more easterly (around 5kts) on Friday. Moderate confidence.
MARINE. Conditions on the marine zones are expected to deteriorate into tonight with Small Craft Advisory criteria after 22Z with with southerly winds from 10 to 15 knots and gusts to 25 knots across the northern two Atlantic zones. Wind gusts will remain near or below 20 knots across the rest of the Atlantic zones and across the Delaware Bay. Winds will lesson early Monday before picking back up Monday afternoon and into the overnight with advisory level gusts out of the south across the Atlantic zones. Gale force gusts may be possible by Tuesday morning, however confidence is not particularly high yet.
Outlook .
Tuesday and Tuesday night . SCA conditions likely especially on the coastal waters through the day Tuesday with southwesterly winds shifting northwesterly in the afternoon, and gusts up to 30 kt possible. Tuesday night, winds and seas should gradually diminish below SCA criteria.
Wednesday . Conditions should stay below SCA criteria, though some westerly gusts above 20 kt are possible.
Thursday . Sub SCA conditions expected with northerly- northeasterly winds gusting 15-20kts.
Friday . Seas potentially increasing above SCA criteria Friday PM but uncertainty is high. Winds becoming easterly and gusting 15-20 kts by Friday afternoon.
