Area forecast discussion, Jul 23, 1:40 PM CST, 2 hours 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 240 PM CDT SUN JUL 23 2006 .SYNOPSIS... A STATIONARY FRONT EXTENDING FROM HIGH ISLAND TEXAS THROUGH PATTERSON LOUISIANA WILL BEGIN A POLEWARD TRANSLATION LATER THIS EVENING. FURTHER EAST, THE CLOCKWISE CIRCULATION, ATTENDING THE BERMUDA HIGH BUILDING WEST THROUGH THE NORTHERN GULF OF MEXICO, WILL MAINTAIN THIS POLEWARD TRANSLATION INTO MONDAY. THE TRANSLATING AND DIFFUSING WARMFRONT WILL EXIT CENTRAL LOUISIANA MONDAY EVENING. FURTHER-UP, A LONGWAVE IN THE MIDLATITUDE WESTERLIES EXTENDS FROM THE MIDWEST UNITED STATES TO THE SOUTH, TO COVER MOST OF THE GULF OF MEXICO. A CYCLONIC SHEAR ZONE EMBEDDED WITHIN THIS EXTENSIVE LONGWAVE PATTERN EXTENDS ACROSS THE NORTHERN GULF OF MEXICO ITS ENDPOINTS BEING MARKED BY TWO CYCLONIC EDDIES (THE FIRST NEAR BROWNSVILLE, AND THE SECOND SOUTH-SOUTHEAST OF NEW ORLEANS). && .DISCUSSION... EARLIER THIS MORNING, THE CYCLONIC SHEAR ZONE (AND ASSOCIATED SYNOPTIC-SCALE OMEGAS POLEWARD OF THE SHEAR ZONE) WAS INTERACTING FAVORABLY WITH THE SECONDARY CIRCULATIONS ATTENDING THE STATIONARY FRONT. WIDESPREAD RAIN WITH EMBEDDED THUNDERSTORMS WAS THE RESULT ACROSS SOUTHCENTRAL LOUISIANA. AT PRESENT, THE AFORMENTIONED WEATHER CONFIGURATION IS CHANGING, AS THE CYCLONIC SHEAR ZONE BEGINS TO FADE FROM VIEW. ON MONDAY, A SOUTHERLY AIRFLOW WILL BE EVOLVING AND DEEPENING. BY MONDAY AFTERNNOON, A SLANTWISE ASCENDING AIRSTREAM, ORIGINATING OVER THE CARIBBEAN, WILL BE FLOWING NORTHWARD SUBSEQUENTLY BRANCHING NEAR FREEPORT TEXAS. CONSEQUENTLY, AN ANTICYCLONIC ASCENDING AIRSTREAM, UPGLIDING OVER THE EXITING FRONTAL SURFACE, WILL BE PRESENT ACROSS THE FORECAST AREA. WIDESPREAD RAIN WITH EMBEDDED THUNDERSTORMS WILL BE THE RESULT. I DECIDED TO USE THE GFS QUANTATIVE PRECIPITATION FORECAST FIELDS TO DELINEATE MY RAIN AREAS. THIS GLOBAL FORECAST MODEL WILL MORE CLEARLY SEE THE INCOMING CARIBBEAN AIR (COMPARED TO REGIONAL MODELS). ALSO, I BELIEVE THAT THE MAJORITY OF THE RAINFALL WILL BE IN THE FORM OF LARGE-SCALE (OR GRID-SCALE) RAIN NOT CONVECTIVE (OR SUBGRID-SCALE) RAIN. CONSEQUENTLY, MY RAIN CHANCES WILL BE IN THE LIKELY CATEGORY DURING THE DAYTIME. TEMPERAURES WILL BE A CHALLENGE OVER THE NEXT FEW DAYS DUE IN PART TO THE CLOUD COVER. THE AFTERNOON READINGS WILL BE RUNNING A FEW DEGREES BELOW NORMAL. && .AVIATION... PATCHY FOG IS POSSIBLE IN THE WEE HOURS OF THE MORNING ESPECIALLY ACROSS SOUTHCENTRAL LOUISIANA. && .PRELIMINARY POINT TEMPS/POPS...
