NWS Forecaster Discussion
472 fxus61 kokx 052049 afdokx Area forecast discussion National Weather Service Upton New York 449 PM EDT Sat Jul 5 2008 Synopsis... an unsettled pattern will prevail through at least the first half of next week as tropical moisture interacts with weak disturbances along the western periphery of the Bermuda high. A diffuse frontal boundary just south of the tri-state area this evening will lift north Sunday evening. This will be the primary focus for showers and thunderstorms on sun. Warm and muggy conditions this weekend will be followed by hot weather for the middle of the week. && Near term /until 6 am Sunday morning/... scattered convection continues to fire up this afternoon across interior New Jersey and the lower Hudson Valley where some sunshine has further destabilized the airmass. In addition...a shearing middle level vorticity will be skirting this area through early this evening. While instability is marginal...a deepening moisture profile and light steering will produce localized heavy rainfall through early this evening. The convection is expected to diminish this evening due to the loss of daytime heating...however...sct convection can not be ruled out with the close proximity of the shearing middle level short wave. It will be muggy with overnight lows around 70. && Short term /6 am Sunday morning through Tuesday/... a sub-tropopause ridge parked offshore and a cutoff low over the Ohio Valley will aid the development of airmass thunderstorms sun and Monday. A diffuse frontal boundary just south of Long Island on sun will lift northward as the middle and upper flow backs around to the SW. This will result in high precipitable water air being drawn northward around the western periphery of the western Atlantic ridge...once again posing the threat for localized heavy rainfall. Surface warm front dissipates to the north Sun night as surface winds become SW. Plenty of cloud cover cover over the next couple of days will limit the heating potential. Highs on sun will top out in the upper 70s to lower 80s...then rise into the lower and middle 80s on Monday. A deep-layered SW flow will send 850 mb temperatures to 16c plus on Monday. There may be enough drying in the mixed layer on Monday with a SW flow for NYC and points north and west to become partly sunny. The filling upper low begins to shear out to the NE late Monday and Monday night with scattered convection firing up primarily in the after. Once again...there looks to be a heavy rainfall threat with precipitable waters around 2 inches. However...weak shear and moderate cape could provide a pulse severe event...especially for those locations that see sun. Scattered convection remains in the forecast on Tuesday as the weakening upper trough slides across the area. Partly sunny skies on Tuesday will send interior locations into the lower 90s...and the middle and upper 80s at the coast. Potential for pulse severe thunderstorms will increase with a high cape...weak shear environment. && Long term /Tuesday night through Saturday/... high pressure over the Atlantic will continue to provide the region with a southerly flow. As a result...expect warm and humid conditions to continue across the tri-state area. Temperatures through the period will climb into the upper 80s to lower 90s with dewpoints in the 60s to near 70. Unsettled conditions will continue with the threat of showers and thunderstorms Tuesday night through Thursday.. the best chances for storms will be during the afternoon and evening hours. Drier weather is expected with slightly cooler conditions at the end of the long term period as high pressure builds in to the area. && Aviation /20z Saturday through Thursday/... winds are consistent across the area with directions generally northeast to east and speeds under 8kts. The real challenge is ceilings/visible associated with abundant low moisture and scattered convection. Numerous sites have bounced from VFR to low end IFR within an hour. Expecting the coverage of thunderstorm to increase a bit through the afternoon as middle level clouds break up. Winds will be erratic in/near thunderstorms...but expect gusts to remain below 25-30kts. Winds continue to be light tonight. There may be issues with fog/low stratus after about 07z. NYC terminals should stay MVFR visible...but have IFR ceilings. Outlook for 18z Sunday through Wednesday...very unsettled weather pattern continues. Showers and thunderstorms trek from west to east through most of Sunday. As such...multiple chances for sub VFR ceilings and visibilities in showers and thunderstorms. Front likely moves north as a warm front sometime Sunday with VFR conditions. High pressure remains across the terminals into Wednesday. Monday through Wednesday there will be a chance of showers and thunderstorms as a surface trough develops during the day...and daytime heating increases instability. && Marine... offshore ocean buoys (44025 and 44017) currently reporting seas around 2 feet. See no reason to deviate from the current state with a light east/southeast (5 to 10 kt) flow the next 24 hours. With a frontal boundary just south of the waters through Sunday...winds and seas will remain rather tranquil. The front then lifts north and washes out Sun night followed by a strengthening SW flow. Seas on the ocean are forecast to reach Small Craft Advisory criteria on Monday and remain there into Tuesday as SW winds increase to 15 to 20 knots. A persistent south to southwest flow will continue to dominate area waters through the period. Seas on the ocean will be at or above Small Craft Advisory level through Thursday...as a southerly swell develops. && Hydrology... scattered convection will continue into Tuesday with the potential for localized heavy downpours. The flood threat should be isolated during this time period. && Okx watches/warnings/advisories... CT...none. New York...none. New Jersey...none. Marine...none. && $$ Synopsis...dw near term...dw short term...dw long term...British Columbia aviation...bs marine...BC/dw hydrology...dw
