NWS Forecaster Discussion
Area forecast discussion National Weather Service tiyan GU 724 am chst Monday Feb 13 2012 Synopsis... a trade-wind disturbance and associated inverted surface trough were centered east of the marianas along 150e. Most of the cloudiness associated with the disturbance was located on the east side of the surface trough. However...since forecast issuance time...an area of stratocumulus and isolated light showers has developed on the west side of the disturbance. This area has begun moving into the forecast zones. && Discussion... no major changes to forecast reasoning. Trimmed back onset of isolated showers to later this afternoon and start of scattered showers to around midnight based upon satellite imagery observed during the first half of the shift. Otherwise...no major changes. Best time for scattered showers will be late tonight and Tuesday morning. Satellite imagery and near term model guidance still suggest changes in the structure of this disturbance could require tailoring of the forecast to remove or add portions of the forecast domain from scattered shower coverage. Day shift will need to closely monitor radar and satellite imagery. Next trade- wind disturbance is still expected to move through on Thursday. && Marine... story remains the same. Wave watch model continues to initialize too high. Reduced trade-wind swell to 6 feet today based upon ipan buoy observations. Latest ascat analysis shows sustained winds in the 20 knot range over the marine zones. Still expect lull in wind speeds as the inverted surface trough passes through later this afternoon and tonight. Day shift should be able to drop the Small Craft Advisory on schedule. Winds and seas will increase once again as the trade-wind surge on the back side of the disturbance arrives. A more robust Small Craft Advisory for winds and seas will be needed on Tuesday. A minimal high surf advisory may be required on Tuesday as well. && Eastern micronesia... ascat shows weaker winds associated with a trade-wind surge over the Marshall Islands this morning. A few showers are seen in the kwajalein radar imagery and also on infrared satellite. Models are in general agreement on drying these showers out today with dry conditions remaining in place over Kosrae and Pohnpei through midweek. Ascat shows stronger winds south of Hawaii that will propagate into the region by Tuesday night. Kosrae and Pohnpei could see some showers by the end of the week. An area of enhanced trade-wind convergence should develop near Kosrae by Thursday. Altimetry shows combined seas northeast of the Marshalls have dropped by 1 to 3 feet since yesterday. Therefore...the high surf advisory has been dropped for Majuro. Trade-wind swell and wind waves continue to produce hazardous surf on Kosrae though. Stronger winds will develop east of Majuro by Tuesday and combined seas will will increase in the Majuro marine zone by 1 to 2 feet. Another high surf advisory will be needed for Majuro on Tuesday. && Western micronesia... a convectively active surface trough and embedded circulation south of Yap headline the weather in western micronesia this morning. Deep convection has persisted all night near Yap...but is holding back just east of Koror. Models indicate showers will continue over Yap through tomorrow before sliding westward and passing just north of Koror. However...active convection has been lurking just east of Koror much of the morning. If the trough moves toward the west more rapidly than expected...Koror could see scattered showers and isolated thunderstorms arrive today. Locally heavy rainfall and gusty winds are possible on Yap through Tuesday...and through Wednesday on Koror. Clouds on the backside of this feature continue to pull away from Chuuk...which will see somewhat drier weather for much of the week. Wave watch model indicates fairly high combined seas near Yap and Koror this morning. However...altimetry shows combined seas to be a few feet below initial model output. Surf will remain below hazardous levels on both locations through the week. Chuuk could see hazardous surf by midweek as stronger trades build in. && Gum watches/warnings/advisories... GU...none. Marianas waters...Small Craft Advisory for winds until 6 PM chst this evening for pmz151>154. && $$ McElroy/M. Aydlett
