WATER VAPOR IMAGERY SHOWS SHORTWAVE TROUGH MOVING ACROSS SOUTHERN
NEW ENGLAND TONIGHT.  DYNAMIC CONTRIBUTIONS FROM THIS SYSTEM HAD
HELPED TO ENHANCE SHOWER DEVELOPMENT OVER SOUTHERN PORTIONS OF
VERMONT THIS AFTERNOON AND INTO EARLY TONIGHT.  AS THIS SYSTEM
CONTINUES TO MOVE EAST OVERNIGHT...LOSS OF DYNAMIC SUPPORT COUPLED
WITH STABILIZING ATMOSPHERE...POTENTIAL FOR ANY SHOWERS WILL
DIMINISH.  ACROSS NORTHERN PORTIONS OF NEW YORK AND VERMONT...
SCATTERED SHOWERS THAT DID DEVELOP THIS AFTERNOON WERE PRIMARILY
THERMALLY DRIVEN.  ALBANY SOUNDING FROM 00Z TONIGHT AS WELL AS PAST
COUPLE OF RUNS SHOWED LAPSE RATE TRENDING TOWARD DRY ADIABATIC FROM
950-700 MB.  THE SURFACE HEATING HELPED TO FURTHER STEEPEN THE LAPSE
RATE AND PRODUCE THE INSTABILITY TO GENERATE THE SHOWERS. WITH
STABILIZING LAPSE RATES OVERNIGHT...THREAT FOR SHOWERS WILL COME TO
AN END AS WELL.  CHANGES TO OVERNIGHT PERIOD WILL BE FOR NO MENTION
OF PRECIPITATION AS WELL AS SKIES BECOMING PARTLY CLOUDY.

ANOTHER SHORTWAVE TROUGH MOVING OUT OF THE MIDWEST WILL FOLLOW
NEARLY THE SAME PATH AS LAST SHORTWAVE TROUGH.  THIS WILL RESULT IN
SOUTHERN AREAS HAVING BETTER SHOWER POTENTIAL THAN ACROSS THE NORTH.
SCATTERED SHOWERS SHOULD DEVELOP OVER RUTLAND/WINDSOR COUNTIES AS
THE MORNING PROGRESSES AS 500-300 MB IPV ADVECTION APPROACHES.
OVER THE NORTHERN SECTIONS...FORECAST SOUNDINGS AND PLAN VIEW
DISPLAYS OF 950-700 MB LAPSE RATES...SUGGEST POTENTIAL FOR AFTERNOON
SHOWERS WILL CONTINUE.  THUS WILL ADJUST TIMING OF PRECIPITATION
TO THE AFTERNOON HOURS OVER THESE AREAS AS INSTABILITY DEVELOPS
FROM AFTERNOON HEATING.  REMAINING ELEMENTS OF GOING FORECAST LOOK
REAL GOOD WITH DRYING TREND FOR TUESDAY NIGHT INTO WEDNESDAY AND
WARMER TEMPERATURES BY MIDWEEK.

                        _LSC WEATHER CENTER FORECAST
                       5:00PM, Monday April 19, 1999
                    STUDENT METEOROLOGIST: Jeremy Davis_
       _** The latest forecast for Northeast & North Central Vermont**
       ** The area bounded by Waterbury, St. Johnsbury, and Newport**_


   _
   Tonight: Early evening cloudiness and showers will slowly break up and
   will yield to partly cloudy skies overnight. Look for low temperatures
   of 30 to 35 with light winds.

   Tuesday: Increasing clouds with some showers developing during the
   afternoon. Most of these showers will be quite light however. Highs
   will be on the cool side, around 50 degrees. Winds will blow lightly
   out of the north.

   Tuesday Night: Some showers will linger during the evening, otherwise
   cloudy. Lows will bottom out in the middle 30's under light winds.

   Wednesday: Mostly cloudy but warmer. Highs will climb to the upper
   50's under southwest winds of 5 to 10 mph.

                             Extended Forecast

   Thursday: Mostly cloudy with scattered showers. Mild with highs of 60
   to 65 and lows of 40 to 45.

   Friday: Partly cloudy with still a chance of a shower. Remaining mild
   with highs in the lower 60's and lows in the middle 40's.

   Saturday: Partly to mostly cloudy with more scattered showers. Look
   for highs around 60 with lows around 40.

                            Forecast Discussion


   The widely scattered showers of today will come to a quick end during
   the evening tonight as skies clear with a small bubble of high
   pressure. As we look to Tuesday, a weak low pressure system will be
   making its move from the Mid-Atlantic region to just south of New
   England. This low will toss a few showers our way, but most of the
   rain will be on the light side. After this low moves off to the
   Canadian Maritimes, our attention will turn to an approaching warm
   front from the SW. This front will help to boost our temperatures but
   will also keep the threat of scattered showers all the way through the
   first half of the weekend. This is good news as the Northeast Kingdom
   is still lacking in the rainfall department.
