NWS Forecaster Discussion
949 fxus61 kbox 240107 afdbox Area forecast discussion National Weather Service Taunton Massachusetts 907 PM EDT Wednesday Jul 23 2008 Synopsis... a slow moving cold front will bring heavy rainfall and possible flooding to portions of southern New England through Thursday evening. A second cold front will approach late this weekend with another round of showers and thunderstorms possible. Unsettled weather will remain across the region through early next week. && Near term /until 4 am Thursday morning/... threat of severe thunderstorms seems to be diminishing slightly. Current plan is to keep the thunderstorm watch in effect until 10 PM. Will reevaluate this watch in the next 30 minutes. Very heavy rainfall continues with these showers and thunderstorms... with localized urban or flash flooding likely. && Short term /4 am Thursday morning through 6 PM Thursday/... anomalous late July pattern with upper low amplifying across Great Lakes and acquiring some negative tilt. Slow moving cold front will be focus for very heavy rainfall...but locally heavy rain also possible east the boundary as we are witnessing currently in high precipitable water airmass. GFS/NAM/ECMWF and all gefs ensemble members in reasonable agreement on axis of heaviest rain setting up across our west zones...especially CT valley and Berkshires. Amounts differ but general location is similar so we have enough confidence to issue Flood Watch for west zones and extending it eastward to S New Hampshire...orh County and Rhode Island/CT border. Highest confidence of flooding rains will be over CT valley and Berkshires. NAM indicating up to 10 inches across west zones while GFS/European model (ecmwf) show up to 5 inches. Gefs ensembles Show Low level jet +4sd for 24h period which suggest persistent inflow and intense low level convergence along frontal boundary. Given slow movement of front...we cant completely rule out localized 8" with widespread 2-5" amounts in watch area...highest CT valley and Berkshires. Further east in the coastal plain...our best estimate is for 1-2". We focused highest probability of precipitation in west zones...then decreasing to the east. Given high amplitude pattern much of the rain may remain west of cape/islands through Thursday and we have just chance probability of precipitation here. Severe weather also remains a concern late tonight and Thursday given very strong low level wind field producing a highly sheared environment. Instability will be limited...but any storms will have to monitored very closely. Any storms stay develop will have potential to become supercells. Surf zone...we issued high surf advisory for Thursday/Thursday night due to increasing south wind wave. Seas will build to 8 feet offshore resulting in a high risk of rips on south facing beaches. && Long term /Thursday night through Wednesday/... models showing less continuity this afternoon...lending to less confidence to this portion of the forecast...especially from Monday Onward. Leaned toward the GFS and European model (ecmwf) ensembles for this portion of the forecast. One thing that appears to show some continuity is the long wave upper level trough that is expected to remain along the eastern U.S. Through at least Tuesday. Thursday night...front moves slowly across the region with likely to categorical shwrs/tstms. Models having difficulty with the timing of this system...though appears that the front will work into eastern Massachusetts by 12z. With high precipitable water values continuing...will also see more heavy rainfall as well. Friday...cold front swings offshore...then stalls S of the region in the general SW upper flow as high pressure remains stalled over the western Atlantic. Some leftover showers will end over eastern Massachusetts in the morning. Dewpoints will drop a bit...but remain in the Lower-Middle 60s as highs head to the lower to middle 80s. Will also remain dry Friday night Saturday...next front begins to approach around the cutoff upper low over Quebec. Timing is suspect as models showing some spread at this point...but have included chance probability of precipitation from west-east during the day. Dewpoints head back up with the continued SW flow. Current timing suggests best shot of showers/thunderstorms will occur during the nighttime hours...but not a whole lot of confidence. Sunday through Tuesday...at this point...appears that the front slows to a crawl as it crosses the region over this weekend...then will push just off the coast on Monday. Have carried chance probability of precipitation through Monday...though still have not a lot of confidence with the timing of this system. Wednesday...appears that it will be a dry day with high pressure trying to push east out of the Great Lakes. However...low confidence due to the very amplified upper pattern in place. && Aviation /01z Thursday through Monday/... tonight... a mixture of MVFR/IFR conditions were observed across southern New England this evening. Conditions will deteriorate to IFR/LIFR across the region overnight. In addition...periods of heavy showers and embedded thunderstorms will continue...especially across the interior. Some of the stronger storms will produce brief gusty surface winds. Thursday... MVFR/IFR continue with periods of heavy showers and embedded thunderstorms. The heavy showers will result in brief vlifr/LIFR conditions along with gusty winds. Outlook...Thursday night through Monday... Thursday night...expect IFR for all locations with rain showers/scattered thunderstorms and rain. Some rain showers will have heavy rainfall. May see some slow improvement over the CT valley after midnight. Friday...conditions gradually improving to VFR...lingering MVFR-IFR conditions possible cape and islands. Sat...VFR early. Conditions lowering to MVFR-IFR in scattered rain showers/thunderstorms and rain from west-east during the day. Sun and Monday...IFR am/MVFR PM scattered rain showers/thunderstorms and rain and fog patches S coast each day. && Marine... southerly winds will increase late tonight and Thursday as low level jet develops. Low level inversion will limit mixing but 40-50 kts just above the surface should allow for g25 kts. Undercut wnawave guidance as it is exhibiting its high bias in south flow. Swan output looked much better with seas building to 8 feet Thursday on outer waters. Outlook...Thursday night through Monday... Thursday night and Friday...expect Small Craft Advisory for hazardous seas expected with building southerly swell. Wind gusts to 25 knots possible Thursday night. Undercut wna guidance slightly given low level inversion and an overforecast bias on the S swells. Saturday and Sunday...Small Craft Advisory for hazardous seas will continue with building S-SW swell expected ahead of the next approaching cold front...mainly on the southern waters. Monday...winds shift to west and diminish. Leftover seas will remain close to small craft criteria on the southern outer waters. && Hydrology... quantitative precipitation forecast amounts will vary across our region. Maximum amounts expected over CT valley and Berkshires with 2-5 inches and locally 8 inches possible through Thursday night. Amounts decrease to the east with generally 1-2 inches across the coastal plain...and less across the cape and islands. Flood Watch has been issued due to this threat. Urban and poor drainage flooding likely along with river and small stream flooding...highest risk CT valley and Berkshires. && Box watches/warnings/advisories... CT...Flood Watch through late Thursday night for ctz002>004. Massachusetts...Flood Watch through late Thursday night for maz002>004-008>012- 026. High surf advisory from 8 am Thursday to 8 am EDT Friday for maz020-023-024. New Hampshire...Flood Watch through late Thursday night for nhz011-015.
