A cold front crosses the region today and moves East of the
chesapeake bay Saturday night. High pressure moves back into the
area Sunday and remains in control through the middle part of
the upcoming work week.
NEAR TERM /UNTIL 6 PM THIS EVENING/
A cold front moving through the midWest early this morning will
bring another shot of cooler air to us. But not before we
squeeze in a warmer than normal day today, although clouds will
be on the increase. The front will bring little if any precip to
the area. Currently thinking there will be a few sprinkles East
of the mountains and thats about it. Mos guidance of nearly all
sorts keeps pops below 10 percent, and convective allowing meso
ensembles and models show varying degrees of small broken bands
of very weak echos moving East across the region.
SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/
Behind the frontal passage, West to NorthWest winds will
increase appreciably Saturday night, resulting in upslope rain
showers transitioning to snow showers during the evening in the
favored locations, with minor accumulations of an inch or less
possible thru sunrise Sunday. Temperatures will settle down in
the 30s for most, near 40 degrees in the cities, and some upper
20s in the Western highlands.
breezy conditions Sunday morning will start to subside during
the afternoon has high pressure builds in from the West
SouthWest. Expect dry conditions to finish out the weekend with
highs in the mid to upper 40s, to near 50 in the metro area. Low
temperatures Sunday night will fall down in the mid to upper 30s
LONG TERM /TUESDAY THROUGH FRIDAY/
On Tuesday, an upper level ridge axis will be over our region. At
the surface, high pressure will be centered just off the coast, with
broad SouthWesterly flow over our region. This will result in mild
conditions with temperatures perhaps topping 60, and no
precipitation is expected.
a Northern stream shortwave trough will pass by to the North Tuesday
night. The high will slip a bit further East and stretch out to our
South, with winds turning a bit more Westerly as a weakening cold
front approaches from the NorthWest. It will remain mild with lows
staying above freezing, but no precipitation is expected.
the Northern stream shortwave trough will move away to the NorthEast
Wednesday as another ridge axis approaches from the West. The cold
front moving in from the NorthWest on Tuesday night will stall and
die out as surface high pressure rebuilds over the region. Mild and
dry conditions will continue to prevail.
a ridge axis will move overhead Wednesday night as a Southern stream
shortwave begins to approach from the SouthWest. At the surface,
high pressure will remain in control as it shifts NorthEastward
across the area. With mild air mass remaining in place, temperatures
will likely stay above freezing in most areas once again.
the ridge axis will move NorthEast of us on Thursday as a much
stronger shortwave trough dives SouthEastward over the midWest and
the Southern stream shortwave weakens over the carolinas. Surface
high pressure will retreat Eastward off the coast as a cold front
approaches from the NorthWest. Increasing clouds will likely limit
warmth by this time, with temps less likely to reach 60, and the
chance for rain, though low, will start to creep up.
the Southern stream shortwave will pass off the East coast Thursday
night as the deepening trough to our West continues to approach our
area. The approaching surface cold front will begin to enter our
area. Mild temperatures will remain (in fact likely the mildest
night of the week thanks to cloud cover), but the chance of rain
will increase substantially.
the strong upper level trough and surface cold front from the
midWest will cross the region Friday. Temperatures will slide back
towards normal and the chance of rain will linger.
AVIATION /09Z SATURDAY THROUGH WEDNESDAY/
Vfr conditions expected across the terminals for the next 24
hours. Clouds will be on the increase with the cold front today
but vfr vis/cigs expected as any shower activity will remain
limited. The cold front will pass through the terminals during
the afternoon and exit to the East Saturday evening. Winds will
turn gusty out of the West NorthWest tonight, averaging 10 to
15 knots with gusts up to 20 knots. Winds will subside during
the day Sunday with clearing skies and dry conditions forecast,
thus no flight restrictions expected. Vfr conditions are
expected to prevail through Wednesday as high pressure controls
our weather pattern.
Light South to SouthWest winds today will turn Westerly later
today following the cold front. Small craft advisory conditions
expected to begin this evening and continue through Sunday as
gusty NorthWesterly winds increase behind the front.
conditions on the waters should remain below sca levels on Monday.
Tuesday, Southerly channeling on the back side of the high may
result in small craft advisory conditions. These may continue
Wednesday as a weak cold front pushes into the region.
marine...Small craft advisory from 9 pm this evening to 5 pm est Sunday
