NORTH JERSEY WEATHER OBSERVERS MEETING - Wednesday, June 28, 2000

The meeting was called to order at 8:15 p.m. by Vice President Art

Petridis. Outside it was about 72 degrees and raining.

The June issue of the Weather Shelter was distributed to the eight members attending. The remaining will be in the mail tomorrow. Editor Jason Hayday would like to see the newsletter delivered prior to the monthly meetings.

The minutes of the May meeting were approved as printed.

The club's equipment has still not been returned from former editor Ken Davis. Art Petridis would like a letter sent to him, or other action taken.

Greg Petridis reported few calls to the hotline. Bob Ziff sent an

e-mail report that our data was used twice in the newspapers this month.

President Keith Galley, who couldn't attend the meeting, has programs

lined up for the meetings the next few months. For July, we will go as a group to see the new movie, "The Perfect Storm." Current plans are to meet at the regular meeting location to car pool. Check the newsletter, hotline, web site, or contact an officer for later details. Keith will arrange a tour of WWOR, Channel 9, in September.

After some discussion of recent weather, we watched some weather

programs recorded from a cable station's series.

Secretary

MONTHLY SUMMARY - JUNE, 2000

KING OF PRUSSIA, PA.

Weather conditions during June were nothing unusual in the King Of Prussia area. Heat & humidity prevailed, interspersed with brief cool spells, and rainfall totaled near normal (4.62”). High temperatures peaked in the 80s & 90s on 22 days; the months average was 72.2 degrees. Thunderstorms occurred on 5 days.

The month started out summer-like with highs around 90 and gusty south-west winds under sunny skies. On the evening of the 2nd, a dying line of thunderstorms associated with an incoming cold front produced 25-35mph, WNW wind gusts and just a spit of rain. The initial strong gusts of wind created a local dust storm that came from nearby construction sites.

Temperatures turned more seasonable from the 3rd-5th with highs in the 70s and lows down into the 50s. Weather conditions on the 3rd were exceptionally nice. Sunshine prevailed throughout the day along with low humidity and gusty, cooling breezes. On the 6th into the overnight hours on the 7th, a rare June nor’easter caused rain, gusty east-north winds and cool temperatures. Rainfall totaled less than 3/4 of an inch in King of Prussia, accompanied by winds gusting between 20 & 30mph.

Sunshine dominated while increasingly hotter & humid conditions set in from the 7th through the 11th. Daily high temperatures progressed from 79 to 94 and lows from 50 to 70. In King Of Prussia, new record highs were established from the 9th-11th with readings of 90(tie), 92 & 94 degrees respectively.

On the 12th, showers & a weakening heavy thunderstorm accompanied the arrival of a back door cold front during the late afternoon & evening, producing 1.25-1.50” of rainfall. Most of the precipitation occurred within 45 minutes. On the 13th & 14th, cloud cover, ENE winds and unseasonably cool temperatures prevailed while occasional drizzle, some light rain & fog were experienced. Temperatures were more typical of early May and did not vary much, ranging from 57 to 64 degrees. Overnight drizzle & morning cloudiness gave way to partial sunshine on the

15th along with increased heat & oppressive humidity. A shower & a thundershower occurred toward midnight. Similar weather conditions prevailed on the 16th except that it did not rain.

On the 17th, scattered thunderstorms that accompanied the movement of a disturbance from the west weakened as they moved through the area late in the afternoon. Just a few minor rumbles of thunder were heard and a brief sun shower occurred. On the 18th, heavy-severe thunderstorms & showers developed along a nearby frontal boundary from mid afternoon through early evening, dropping between 1:00-1:50” of rain. The first thunderstorm of the afternoon grazed King Of Prussia to the south, yielding frequent thunder & rainfall totaling a few hundredths. Doppler radar indicated rotation within the storm prompting issuance of a tornado warning for parts of neighboring Delaware County. None were reported, however. Heavy rain, frequent lightning & thunder accompanied intensifying thunderstorms & showers toward early evening. Approximately an inch of rain fell within an hour, causing some minor street flooding. Additional showers occurred later in the evening.

Following three dry days a weakening line of showers & thunderstorms accompanied the passage of a cold front late on the 21st into the 22nd. Rainfall measured more than 3/4 of an inch. Heat & humidity reigned from the 23rd-27th with almost no rainfall occurring. Heavy thunderstorms in central Pennsylvania on the 25th dumped from 3.00”-5.00” in western Berks county. A surviving shower moved through the local area early in the morning on the 26th, leaving 0.03” of rain. Late in the afternoon a thundershower passed by to the north. An expected development of severe thunderstorms on the 27th failed to materialize even though a fairly strong cool front pushed through the region late in the day. Surprisingly, no rain fell at all.

On the 28th, the front was close enough to the south to allow a shield of rain moving along it to affect the area from late afternoon through early evening, producing a 1/2 inch. Marginally unstable

air on the 29th led to the development of shower late in the afternoon. On the 30th, sunshine, cooling breezes and low humidity were experienced with an afternoon high of 81 degrees.
