SYNOPSIS. A cold front and developing low pressure system will cross the region tonight, then linger off the coast on Tuesday. High pressure will slowly build overhead Wednesday. Another storm system will approach from the southwest Thursday and overspread the region Thursday night and Friday. This system will linger nearby into the weekend.

NEAR TERM /THROUGH TUESDAY/. Latest surface analysis depicts a warm front extending westward across New England, New York and the eastern Great Lakes to a low pressure developing in Ohio. A cold front extends southwest from that low towards the western Gulf Coast. Meanwhile, another low pressure is developing off the Carolina coast, heading northward. Aloft, a closed low is moving eastward over Indiana with another shortwave over the Carolina coast. Sensible-weather wise, conditions remain dry presently, but showers and storms are approaching from both the south and the west. Presently, the storms from the south are the stronger, but this may change as the evening progresses and the front interacts with the warm and humid (for late October) air mass over our region presently.

With a modest amount of CAPE available but exceptional amount of moisture (for late October) and plenty of forcing aloft, expect showers and storms to blossom over the region during the next several hours. This will be in concern with the low pressure over Ohio redeveloping on this side of the mountains in our general vicinity. With adequate wind aloft and the strong forcing, expect at least some isolated severe storms, and both locally heavy rain and an isolated tornado are possible given decent shear and potential for some training. Given dry antecedent conditions, did not hoist a flash flood watch, as think the flood risk is fairly isolated.

System mostly pushes northeast of us late tonight, with rain tapering off and some breaking clouds. This may allow some patchy fog to develop late tonight. Lows mostly in the 50s.

On Tuesday, we start of relatively tranquil as the low pressures to our northeast consolidate. It appears the low to the south will become the main low pressure and strengthen significantly as it hangs a left and heads back towards the coast, with the low closer to the coast merging into it. This will result in increasing winds through the day, along with showers sliding back southwestward into the region. Currently have winds staying just below wind advisory for most of the area, except for the ridges where we brush criteria. However, it won't take much for winds to reach low end advisory across the metro, though showers could keep things just stable enough to limit the risk. Highs will be in the 60s, but with the wind and showers, it will feel colder.

SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/. Low pressure gradually shifts east off the coast Tuesday night through Wednesday night as surface high pressure and ridging aloft builds eastward. This should allow winds to start subsiding, showers to dissipate and clouds to slowly break. By Wednesday afternoon, mostly sunny skies with a breeze are expected. Still lighter winds and mostly clear skies will prevail Wednesday night, with lows mostly in the 40s.

LONG TERM /THURSDAY THROUGH MONDAY/. For now, Thursday looks relatively dry ahead of our next weather system slated to impact the region on Friday. A large upper level low will continue to deepen on Thursday before becoming cut off from the parent jet stream. Clouds will generally increase Thursday as the low's associated warm front lifts northward ahead of the system. Rain will begin developing from SW to NE late Thursday into Friday as the system tracks eastward. Appears more likely with time that this system will deliver a soaking rain, along with gusty winds to the region. PWAT anamolies are either at or exceed 2 inches across much of the region. Coupled with an easterly wind, increasing moisture into the area, could see a widespread 1-2+ inch event for most with locally higher amounts possible, especially for portions of central VA and along the Blue Ridge. Wind gusts will range between 30-50mph would could cause scattered power outages and downed tree limbs in the worst case scenario . On a positive note, the low is rather quick moving. Thus appears that the bulk of the rain will fall during the morning hours on Friday before tapering off to light rain by the afternoon/evening.

Saturday is more of a transition day. As the low continues to track off to our northeast, drier weather is expected with the exception of some residual showers along the PA/MD border and Alleghenies with upslope showers persisting. However even those areas are likely to see improvements by late in the day. High pressure returns for Sunday. Temperatures throughout the long term period will be near seasonable levels in the low to mid 60s for most, cooler across the higher terrain.

AVIATION /19Z MONDAY THROUGH SATURDAY/. VFR conditions presently will not last, as showers and storms from the approaching system to the west and south overspread the region over the next few hours. Brief IFR possible in heavy rain, along with strong wind gusts of 30-50 knots possible. Storms should move away after midnight, but patchy low clouds and fog will be possible. On Tuesday, some wraparound showers may result in restrictions at times later in the day into the evening, while strong northwest winds likely gust 30-40 knots at times. Winds start to relax with clearing skies by Wednesday.

MARINE. Marginal SCA gusts currently ahead of approaching cold front. Winds should diminish this evening, but strong to possibly severe storms may required special marine warnings. Quiet weather will encompass the waters for a time late tonight, but winds will increase from the northwest through the day Tuesday as low pressure strengthens rapidly just off the coast. Gale Warnings in effect for a good chunk of the bay and adjacent waterways, and may need expansion to all remaining waters. Gales should diminish early Wednesday, but winds should remain in SCA range thru the day before slowly diminishing Wednesday night.

TIDES/COASTAL FLOODING. Although southerly flow continues, anomalies have mostly leveled off, so while we will again see tides near minor thresholds this evening, do not think they will reach flood stage. However, will need to watch them closely. Water levels should decline Tuesday into Wednesday as northwest flow drains water out of the bay. This will not last long, however, as the next low pressure will move northward bringing a strong and widespread easterly flow later Thursday into Friday. This looks strong enough to potentially result in some moderate coastal flooding, but uncertainty is still high considering it is several days out. Will watch this threat very closely in the coming days.
