Synopsis
Northeastward moving low pressure from the upper great lakes to
missouri will pull a warm front northward through the DELMARVA and
southern new jersey today. The warm front should stall across
southeastern pennsylvania and central new jersey, awaiting the
passage of the missouri low, through new jersey, Tuesday evening.

Thereafter, canadian high pressure will build into our area
Wednesday and Thursday. Low pressure in the ohio valley on Friday
will move east and off the mid atlantic coast on Saturday. Weak
high pressure should follow on Sunday.

Near term /until 6 pm this evening/
Few minor tweaks at 630 a.M. Added coastal atlantic county to
dense fog advy. It was mistakenly left out earlier. Also dropped
sussex de from advy since vsbys there have improved. Minor
downward adjustment to temps in metro philadelphia and n/w for
today.

A slow moving warm front will be tracking across the area today.

Our forecast has trended slower with the frontal passage and
includes a slower trend in improvement (sunshine) behind the
front and slightly lower temperatures for today. We have issued
a dense fog advisory for DELMARVA and parts of se/pa and SRN nj
for the early part of the morning, since the vsbys continue to
trend downward and are 1/2 sm - 3/4 sm attm. The onshore flow
will continue in these areas until the front passes later today.

The low clouds and areas of dense fog will be over the area
thru the first part of the morning before a S to N slow
improvement trend is expected today. Areas across the lehigh
valley and southern poconos may see improvement late this
afternoon. Confid in the n/w areas is limited attm. The low
which the warm front is attached to is weak, so it's possible
that the topography of these areas may play a factor slowing the
motion. Highs today are expected to reach the upper 60s/low 70s
over south nj and delmarva, low/mid 60s in central nj , metro
philadelphia and lehigh valley and 50s north of that.

Short term /6 pm this evening through 6 am Tuesday/
Hopefully the warm front will have moved far enough away to have
a lull in the precip for the evening. More showers will arrive
overnight as the next short wave approaches from the w/sw. Pops
increase back to the chc range overnight, favoring slightly the
srn nj and DELMARVA areas. Mild with lows in the low 50s s/e and
mid/upper 40s n/w. Light winds expected.

Long term /Tuesday through Sunday/
500 mb: a split flow regime will continue across the united
states during this period. A short wave crosses pennsylvania
Tuesday and then phases with a northern stream system into a
closed low over the maritimes Wednesday night. The next southern
stream short wave in the pipeline over the mississippi valley
Thursday night, weakens eastward off the mid atlantic coast
Saturday. Yet another southern stream short wave will be moving
eastward from the lower mississippi valley early next week.

Temperatures: calendar day averages should be about 5 degrees above
normal Wednesday, near normal Thursday and normal to 5 degrees
below on Friday, and then normal or several degrees above on
Saturday and Sunday.

Forecast basis: 50 50 blended 00z/27 gfs/nam MOS Tuesday-
Wednesday, then 00z/27 mexmos Wednesday night-Thursday and
thereafter wpc guidance Thursday night-Sunday.

The dailies...

Tuesday... The position of the warm front Tuesday will probably
result in a wide range of temperatures across our area with
large error potential i-78 region northward where global models
are warm but the ever improving 12km NAM and its downscaled 3km
temperatures, are much cooler. Dreary north of that warm front
with patchy dense fog possible and a likelihood of heavy showers
during the afternoon and evening as the missouri low cuts east
along the mason dixon line, heading for a nj seaward exit
Tuesday evening. There could be afternoon and evening
thunderstorms with this short wave. Within the warm sector in
advance of the cold front, we expect sunshine to break out south
of the warm front with temperatures reaching the upper 70s. A
low- level moist tongue will also be in place across this area,
ml CAPE (400-800j), along with negative lifted and showalter
indices, within an environment characterized by poor lapse rates
and weak shear. Thunder is expected but despite the warm
front,right now svr is not. Do follow later phi and spc
discussions. Precipitable water values around 1.25 inches,
should yield some heavy showers near the path of the low.

Movement should be east northeast and there could be some
training and backbuilding along the warm front so that this may
need to be monitored for narrow bands of poor drainage street
flooding rain Tuesday afternoon/evening. Winds light northeast,
north of the warm front (near i-78) and southerly in the warm
sector DELMARVA and S nj. Confidence: above average except the
location of the warm front and the associated temps near the
warm front.

Tuesday night... Showers still may be heavy in the evening (still
thunder possible?), then end from west to east late and the
wind turns north everywhere. Confidence: above average.

Wednesday... A gusty northerly flow to 25 mph of cold air
advection. Dry. Confidence: above average.

Thursday... A sunny start, then increasing clouds and cool ahead
of the next storm system. Light wind. Confidence: above average.

Friday... Increasing model consensus that this actually looks
like a decent little mid atlantic coastal storm with one half to
1.5" of qpf, and currently, only a slight chance of a little
wet snow near and north of i-80 since models have trended
slightly northward.

Friday evening tides may exceed the minor advisory threshold
along the nj atlantic coast provided the sfc low passes south
of acy.

Overall Friday confidence: above average.,
Saturday... Precipitation(mainly rain) ends, but clouds may
linger since there doesn't seem to be much in the way of high
pressure following the low. Confidence: average
Sunday... Considerable cloudiness. Low confidence on what might
transpire this day.

Aviation /12z Monday through Friday/
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

The latest issuance of the tafs are somewhat more pessimistic with
regards to how fast the transition back to MVFR thenVFR occurs
today. Warm fronts are usually known for their stubbornness for
improving conditions and this seems to be the case for today. A
decent SW flow aloft argues for the fact that when things begin to
improve, it should happen quickly, but what time that happens is the
problem for the day. The showers that the models show arriving this
morning may mix up the low clouds and fog enough to get the process
going. Winds will be erly prior to the warm front the SW behind it.

Vfr will probably be across the del valley and delmarva/south nj
this afternoon, conditions may remain MVFR across krdg/kabe longer.

Probably a period ofVFR this evening, the more low clouds/showers
late tonight.

Outlook...

confidence: above average all days. Exception being the details of
the warm frontal position Tuesday and timing of poorest conditions
where there is less than average confidence.

Tuesday... Ifr or MVFR conditions Tuesday morning at all TAF sites,
with improvement toVFR by afternoon at all but abe, rdg, and ttn
where ifr may may linger all day. Showers become widespread in the
afternoon/evening with light northeast flow at abe, rdg, ttn and
light south or southeast flow elsewhere. Isolated tstms expected.

Tuesday night... MVFR possible early in showers, otherwise becoming
vfr late. Winds becoming north everywhere late.

Wednesday... MostlyVFR. North wind gusts 20-25 kt.

Thursday...VFR. Light north wind.

Friday... Ifr or MVFR conds in periods of rain. Mostly east wind
ahead of the low.

Marine
We will continue with the SCA flag for seas around 5 ft seas today.

The erly flow will be weakening with time as the warm front slides
northward today. I could see the flag being dropped earlier, but
we will keep it for now. Dense fog on the waters this morning with
the warmer and more humid air arriving across the cold water.

Scattered showers later this morning may stir vsbys up. More sct
showers expected tonight. Patchy fog tonight.

Outlook...

Tuesday... Fog may be marine hazard? Otherwise no SCA expected at
this time. Thunderstorms could occur, especially late in the
day. Confidence: average.

Tuesday night... SCA northerly flow may develop late. Confidence:
average.

Wednesday... Northerly flow sca. Confidence: above average.

Thursday... No headlines. Confidence: above average.

Friday... SCA potential as low pressure heads for the mid
atlantic coast. Confidence: above average.

Climate
Georgetown 3/28 rer MAX is 80 set in 1960.

Phl temperatures continue to project near 1 degree f below
normal for the month as a whole.

Equipment
Knel appears to be reading 10f too warm the past couple of
days.
