SYNOPSIS. A cold front will approach this afternoon before passing through tonight into early Saturday. High pressure will build overhead Saturday night through early next week. A warm front will move through the area Wednesday and a weak cold front will stall out near the region late next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. A Severe Thunderstorm Watch is in effect until 9 PM for north- central and northeastern Maryland (including the city of Baltimore) as well as portions of northern Virginia and eastern West Virginia. Severe thunderstorms are expected across the area this afternoon. Strong heating has occurred beneath a mix of sun and clouds this morning into early afternoon, allowing temperatures to climb into the mid 80s. Rich low-level moisture is also in place, with dewpoints in the upper 60s to low 70s. This combination of high temperatures and dewpoints, coupled with height falls aloft have created ample instability across the area. MLCAPE values have climbed to 1000-2000 J/kg across much of the area, and are expected to max out between 1500 and 2500 J/kg this afternoon. A shortwave disturbance embedded within a larger scale trough is evident on water vapor imagery across portions of WV/KY/OH. Ascent ahead of this feature has led to the development of mid- high level clouds and stratiform rain extending from the Allegheny Front southward toward southwestern Virginia. A surface trough is evident along the I-81 corridor from just west of HGR to Shenandoah County, VA. Storms are starting to fire in this surface trough along the periphery of the large scale forcing associated with the mid- level shortwave over WV/KY/OH. These storms are expected to increase in intensity over the coming hours. An additional convergence line is noted in satellite imagery from Charles County up to Harford County in Maryland. Convergence along this feature appears to be driven both by synoptic scale influence and a weak bay breeze (more so on the northern end). Storms are also starting to initiate along the southern end of the convergence line from Charles County southward toward Richmond.

Confidence in additional thunderstorm development is highest along the convergence line across WV/MD along the I-81 corridor, but storms can't be ruled out anywhere across the area this afternoon into this evening. In terms of convective mode, the deep layer shear present will be sufficient to organize storms into multicell clusters or lines as hinted at by CAM solutions. The shear magnitude will also be sufficient for the development of isolated supercells. Most model soundings indicate either straight line hodographs, or slight counter-clockwise turning in the low to mid-levels, suggesting that it might be difficult for right moving supercells to become established, at least initially. Supercell splits can't be ruled out either, with the near straight line hodograph. There's a fair amount of both CAPE and shear in the hail growth zone, so think that severe hail will be a possibility in the strongest storms. Damaging winds will also be a potential hazard with storms that develop strong downdrafts. The low-level wind field will be on the weaker side initially, and with the straight line hodographs in place, little SRH will be available to right-moving supercells. As a result, the tornado threat is expected to be near non-existent during the mid afternoon hours. The low-level wind field does uptick slightly moving toward evening. While an isolated tornado can't be ruled out this evening, damaging winds and hail are by and large expected to be the primary threats.

Most of the initial thunderstorm development is expected to be along the surface trough near the I-81 corridor, as well as along the convergence line/bay breeze to our east. Activity will progress further east through the late afternoon and evening, but questions remain about the areal coverage of storms as they work toward the metro areas this evening. The highest confidence zone for severe thunderstorms based on both CAM solutions and environmental factors appears to be across northern Maryland. Thunderstorms are expected to decrease in intensity after dark, but may linger across the area until around midnight. Additional thunderstorms are expected to develop along the system's cold front in Ohio this afternoon. These storms will largely fall apart before they reach the mountains, but a few additional showers can't be ruled out overnight in association with this activity as the cold front progresses southward through our area.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/. The surface cold front will continue to slowly work southward across the area on Saturday, but may get hung up across portions of central Virginia and southern Maryland. If the front doesn't progress out of the area, showers and thunderstorms could form along the corridor from Charlottesville to Fredericksburg to St. Mary's County. Elsewhere, skies should gradually clear out throughout the day, with dewpoints dropping into the 50s and high temperatures maxing out in the upper 70s to low 80s. A deep trough will dig southward toward our region Saturday afternoon into Saturday Night, driving a reinforcing cold front through the area Saturday Night. Much cooler and drier air will be ushered into the area in the wake of the reinforcing cold front. Sunny skies are expected on Sunday, with highs in the upper 60s to low 70s and dewpoints dropping into the upper 30s and low 40s.

LONG TERM /MONDAY THROUGH FRIDAY/. High pressure will remain overhead Monday through Monday night, bringing dry and mild conditions along with low humidity. High pressure will move offshore Tuesday through Tuesday night while a warm front approaches from the west. Mild conditions will continue, but there will be more clouds and perhaps even a couple showers ahead of the warm front. Any rainfall will be light and much of the time should turn out dry.

The warm front will pass through Wednesday, and it will turn out hotter and noticeably more humid behind the boundary. A west to northwest flow aloft combined with the increased heat and humidity will lead to a chance for showers and thunderstorms. A northwest flow aloft does favor a possible MCS, but confidence is very low this far out. Will continue to monitor.

A zonal flow is expected aloft for Thursday and Friday while a weak nearly stationary boundary sets up near the Mason-Dixon Line. The boundary will separate lower humidity from higher humidity. A couple showers and thunderstorms are possible on the warm side of the boundary.

AVIATION /19Z FRIDAY THROUGH WEDNESDAY/. Conditions at the terminals have improved to VFR early this afternoon. Expect conditions to remain VFR for the remainder of the afternoon. The main concern today will be thunderstorms. Confidence is highest in thunderstorms impacting MRB. By late afternoon into the evening hours, storms may impact the major hubs, but confidence on the placement of the storms is low, and coverage isn't expected to be overly high. As a result, we have introduced a TSRA TEMPO at MRB, but have maintained VCTS at the rest of the terminals. The threat for thunderstorms at the terminals should gradually wane after dark, with the threat coming to an end around midnight. Development of patchy fog can't be ruled out overnight where it rains, but currently leaning against this scenario given a light gradient wind being maintained overnight. Outside of any thunderstorms or areas of patchy fog, conditions should remain VFR overnight. VFR conditions will continue this weekend in the wake of a cold frontal passage.

High pressure will bring VFR conditions Monday and Monday night. A warm front will approach from the west Tuesday through Tuesday night. A shower cannot be ruled out, but much of the time should be dry and VFR conditions are most likely.

The warm front will pass through Wednesday, and more humidity will lead to a chance for showers and thunderstorms.

MARINE. Southerly winds will increase to SCA levels early this afternoon, and an advisory is in effect for all waters. Outside of the low-end SCA gusts, higher gusts may be possible this afternoon and this evening in association with thunderstorms. Special Marine Warnings may be needed if these storms impact the waters. A cold front will progress over the waters tonight, with winds shifting around to northwesterly behind the front. Winds will be sub-SCA in magnitude on Saturday, but could increase to SCA levels again Saturday Night into Sunday within northerly flow behind a reinforcing cold front.

High pressure will build over the waters through Monday night. Northwest winds will be close to SCA criteria Monday into early Monday.

A warm front will approach the waters Tuesday into Tuesday night before passing through Wednesday. An SCA may be needed Tuesday night and Wednesday for west to southwest winds.
