Continued thoughts and well-wishes to all affected by Katrina. For those who care, regarding the Atlantic/Caribbean features HF and Clark have discussed, here is a portion of this afternoon's discussion from the Miami NWS office: GLOBAL MODELS...ESPECIALLY INCLUDING THE GFS AND NOGAPS SOLUTIONS...DEEPEN THE WEAK SURFACE LOW PRESENTLY ANALYZED NEAR 30N/77W EARLY NEXT WEEK. OTHERS SUCH AS THE ECMWF AND CMC ARE LESS ROBUST WITH LOW...HOWEVER THEY STILL INDICATE ELONGATED EAST-WEST ORIENTED SURFACE TROUGH IN ROUGHLY THE SAME AREA. INITIALLY THIS LOW WILL SERVE TO BRING DRIER AND COOLER AIR INTO SOUTH FLORIDA LATE THIS WEEKEND (PERHAPS TEMPS AND DEWPOINTS 3-4 DEGREES COOLER). THE EFFECT ON LATER PERIODS OF THE FORECAST IS MORE UNCERTAIN...WITH RAIN CHANCES POSSIBLY INCREASING BY MID-WEEK SHOULD THIS SYSTEM MOVE CLOSER TO US. |
