area forecast discussion

1254 pm est Fri feb 15 2019

Synopsis
Low pressure north of lake huron will continue to move eastward
today. High pressure will then ridge across the central great
lakes tonight into Saturday night. Weak low pressure will move
along the ohio river valley Sunday into Sunday night. High
pressure then takes back control Monday night into Tuesday.

Near term through Saturday
Only minor changes to sky cover and hourly temperatures have
been made to reflect current trends. Clouds continue to decrease
in coverage with periods of sunshine expected.

Previous discussion...

temperatures will be at their warmest first thing this morning
with temperatures falling for the remainder of the day into the
evening. Most of the precipitation appears to exit before it is
cold enough for any mix with a few snowflakes with the exception
of the snowbelt. Still no impactful accumulation expected. A
secondary push of low level moisture along with a bit of
shortwave energy push southeast across the snowbelt this evening
and this may bring a development expansion of a few
flurries weak snow showers to the far east snowbelt, but by
later in the night there is little convergence left. Again will
have no impactful meaningful accumulations. Temperatures will be
cool and generally in the lower 20s. Saturday will be quiet and
cool with high pressure extending from the midwest and across
the great lakes.

Short term Saturday night through Monday night
High pressure over the great lakes region will keep the area
dry on Saturday night, as low pressure begins entering the
central united states. This low will reach the middle
mississippi river valley on Sunday and extend a warm front into
the forecast area. The front appears fairly weak at this point
and will likely linger near the lake Sunday into Sunday night.

With this, will maintain chance pops, but will taper back likely
pops as coverage is starting to become a concern. The surface
low moves through the ohio valley on Sunday night into Monday
and off the east coast by Monday night. With high pressure
building in behind the low, will keep a mostly dry forecast on
Monday and Monday night. Temperatures will be perhaps a touch
below seasonal averages in the low 30s for highs and teens to
near 20 for lows.

Long term Tuesday through Thursday
The long term forecast period looks like a rinse and repeat of
the short term forecast period. High pressure over the great
lakes region will keep the area dry on Tuesday, as low pressure
over the southern united states begins moving northeast. This
low will extend a warm front close to the forecast area on
Wednesday, but it's too early to tell if it makes it to lake
erie. Regardless, there will be rain chances for most of
Wednesday, lingering into Thursday. The surface low will then
move northeast through the ohio valley on Wednesday night before
departing the area on Thursday and high pressure building back
into the region. This system is originating further south from
the one this weekend, so suspect temperatures to be warmer,
perhaps in the upper 30s to near 40 for highs and mid to upper
20s for lows.

Aviation 18z Friday through Wednesday
Areas of MVFR ceilings continue across the region. Ceilings will
slowly decrease in coverage as they lift toVFR levels. MVFR
clouds could linger across NW pa the longest. This is also the
area where some flurries may occur. Westerly wind gusts subside
this evening and begin to veer to the northwest and north.

Outlook... Non-vfr possible across NW pa on Saturday. Non-vfr
possible again Sunday and Monday.

Marine
A cold front entering the western basin of lake erie this
morning will cross the lake by this afternoon. The frontal
passage will bring strong west winds over the lake today,
subsiding by this evening. A gale warning has been issued for
these strong winds. At this point, it's fairly marginal on the
west end of the lake, but there may be a brief window of 35
knots. Stronger winds are much more assured on the east end of
the lake and will keep the gale warning through the evening for
areas east of cleveland. High pressure will build into the great
lakes region for Saturday and Sunday and allow for light and
variable winds on the lake. Low pressure entering the middle
mississippi river valley on Sunday night will extend a warm
front close to the lake by Monday. Easterly winds will increase
over the lake ahead of the front. Low pressure will move south
of the lake and eventually off the east coast by Monday night
and will allow for winds to come out of the north. High pressure
nudges back into the great lakes region for Tuesday and
Wednesday and bring back more calm conditions on the lake.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... Gale warning until 7 pm est this evening for lez147>149-
167>169.
