In the hours before
Special weather statement, Jul 23, 12:37 PM EDT, 4 hours 17 minutes before
SPECIAL WEATHER STATEMENT NATIONAL WEATHER SERVICE NEWARK NJ 1235 PM EDT TUE JUL 23 1991 ...HUMIDITY RETURNS..LOWER HUMIDITY HEAT RELIEF WEDNESDAY... THE WEAK FRONT THAT BROUGHT SOME TEMPORARY RELIEF FROM THE HEAT SUNDAY AFTERNOON AND EVENING MADE ITS NORTHWARD TREK AS A WARM FRONT LAST NIGHT. THIS SHOULD BRING ABOUT A RETURN TO TEMPERATURES IN THE 90S AND AN INCRREASE IN HUMIDITY. AS A WEAK COLD FRONT APPROACHES US FROM THE NORTH AND WEST TONIGHT SHOWERS AND THUNDERSTORMS WILL OVERSPREAD THE REGION. THESE STORMS WILL BECOME MORE FREQUENT WITH THE LIKELIHOOD OF LOCALLY HEAVY DOWNPOURS AND GUSTY WINDS. THESE STORMS WILL BE FOLLOWED BY THE COLD FRONT WHICH WILL LOWER TEMPERATURES AND CAUSE A SIGNIFICANT DROP IN HUMIDITY. THE RECORD HIGH TEMPERATURE AT NEWARK INTERNATIONAL AIRPORT FOR JULY 23RD IS 100 DEGREES SET IN 1955. THE TEMPERATURE REACHED 90 DEGREES AT 1205 EDT. THIS IS THE 27TH DAY THE TEMPERATURE AT NEWARK HAS REACHED THE 90 DEGREE MARK DURING 1991. ON MONDAY THE TEMPERATURE AT NEWARK REACHED A HIGH OF 89 DEGREES GIVING US A BREAK FROM OUR SEVEN DAY HEAT WAVE. IT RANKS 12TH ON OUR LIST OF LONG HEAT WAVES WITH THE LONGEST BEING 20 DAYS IN A ROW OF HIGH TEMPERATURES OF 90 DEGREES OR HIGHER SET IN 1988. TONIGHT THE LOW SHOULD REMAIN IN THE MID 70S. THERE WILL BE A GRADUAL DECREASE IN THE HUMIDITY TOMORROW WITH THE TEMPERATURES LOWERING TO MORE LIVABLE LEVELS. THOSE WHO ARE AT RISK SHOULD CONTINUE TO TAKE ALL NECESSARY PRECAUTIONS. SOME SUGGESTED TIPS: SLOW DOWN. STRENUOUS ACTIVITIES SHOULD BE REDUCED, ELIMINATED, OR RESCHEDULED TO THE NIGHTTIME HOURS. INDIVIDUALS AT RISK SHOULD SEEK THE COOLEST AVAILABLE PLACE -NOT NECESSARILY INDOORS. IF OUTDOORS -IF THREATENING WEATHER APPROACHES DO NOT STAY UNDER OR IN THE VICINITY OF SHADY TREES. DRESS IN LIGHTWEIGHT LIGHT COLORED CLOTHES WHICH REFLECT HEAT AND SUNLIGHT, AND HELPS YOUR BODY MAINTAIN NORMAL TEMPERATURES. DRINK PLENTY OF WATER OR OTHER NON-ALCOHOL FLUIDS. YOUR BODY NEEDS WATER TO KEEP COOL. PEOPLE AT RISK SHOULD CONSULT A PHYSICIAN BEFORE INCREASING THEIR CONSUMPTION OF FLUIDS. SPEND AS MUCH TIME AS POSSIBLE IN AN AIR CONDITIONED ENVIRONMENT. VENTILATE YOUR LIVING AREAS AS MUCH AS POSSIBLE. ALLOW THE AIR TO CIRCULATE AND MOVE AS MUCH AS POSSIBLE. DON'T GET TOO MUCH SUN. A SUNBURN DOES NOT MAKE THE JOB OF HEAT DISSIPATION EASY FOR THE BODY. FINALLY, PLEASE REMEMBER THE PETS THAT AFFORD US SO MUCH HAPPINESS, COMPANIONSHIP AND PLEASURE. THEY ARE AFFECTED BY THE HEAT ALSO. PUT AN ICE CUBE OR TWO IN THEIR WATER DISH. WCB/GH
