NWS Forecaster Discussion
569 fxpq60 pgum 250545 afdpq Area forecast discussion National Weather Service tiyan GU 345 PM chst Friday Jul 25 2008 Synopsis... an upper low is centered just SW of pagan island near 18n145e... about 100 miles north of where the GFS has it. A weak surface trough is positioned just west of the marianas. Under the influence of these two systems...widespread cloudiness...scattered showers and isolate thunderstorms are found across the marianas waters. With the passage of the trough...the light east winds of this morning have shifted to southeast. && Discussion... both the GFS and UKMET seem to be having a hard time with the upper low...since neither model shows the activity currently affecting the marianas. And neither model shows more than a hint of scattered showers tonight or Sat. But the upper low is clearly a large factor in setting off the current showers...and as it drifts west it should continue to keep showers in the area for another 24 hours or so. In addition...another weak surface trough is due through the marianas during the day Saturday. Thus...have decided to keep scattered in through Sat...then isolate after. Once we get into Sunday and beyond...it gets difficult to distinguish signal from noise in the model output. There is a hint that scattered showers may return Sun night and Monday with another weak trough...but will wait until Sat to get a better look at that. In summary...not a good situation for high-confidence forecasting. && Eastern micronesia... will be added after 5 PM chst. && Western micronesia... will be added after 5 PM chst. && Gum watches/warnings/advisories... GU...none. Marianas waters...none. && $$ Middlebrooke/Edson
