Heat Wave to Continue in Berks

July 23rd, 2016 (Saturday)

Monday Update: Today’s high reached 94 °F equaling the 13th 90-degree day of the month. The max heat index of 110 °F occurred at 3:07 PM. Clouds and a decaying thunderstorm prevented the temperatures from going higher. The 110 °F heat index was the highest since we reached 113 °F on July 19, 2013. Along with the high heat we actually picked up 0.53″ of rain, but even with this we’re still in excess of a 5″ deficit for the year.

Sunday Update: Today’s high reached 94 °F with a max heat index of 97 °F. High level clouds along with normal Cumulonimbus clouds blocked the sun and capped our heat to some extent. Dew-points were also lower today which helped the “feels like” temperature.

Saturday marked the hottest day of the year reaching 98.3 °F, which just broke the old station mark of 98.0 °F from 2011. This officially made it our 3rd heat wave of the season and the most intense. The heat index briefly reached 105 °F at 2:19 PM before some drier air arrived. The extremely dry conditions combined with the afternoon breeze allowed good mixing of the air at all levels. This allowed the temperature to soar even at our higher elevation where we matched the airport’s high of 98 °F (456 ft versus 344 ft at the Reading Airport).

Today was the eleventh 90-degree day of the month with the forecast predicting about 5 more. This would put us at 16 and just short of the station all-record monthly record of 17 from July, 2010. Monday is expected to be the worst day of the heat wave with high humidity returning and temperatures reaching the upper 90’s. This will produce a heat index around 110 °F which is quite dangerous but still well short of our all-time station record of 118 °F from July 22, 2011. In looking back this is the hottest month we’ve had in 4 years and is a very close match to July, 2012.

There is a chance of some rain Monday night, but I’m not counting on it. The heat wave may finally break during the 2nd half of the week which brings us towards the end of July.

High Heat on Tap for Berks and Beyond

July 22nd, 2016 (Friday)

Saturday Update: Hottest day of the year reaching 98.3 °F breaking the mark of 98.0 °F from 2011. The heat index reached 105 °F at 2:19 PM. The extremely dry conditions combined with the afternoon breeze allowed good mixing of the air. This allowed the temperature to soar even at our higher elevation (456 ft versus 344 ft at the Reading Airport).

Friday Update: Clouds have capped the heat today although the high still reached 93°F with a heat index of 101°F at 1:22 PM.

Thursday marked the ninth 90-degree day at the station in July but with dew-points in the upper 50’s it was bearable. Starting Friday the temperature and humidity combination will reach dangerous levels. The forecast is for temperatures in the mid to upper 90’s with heat indexes peaking near 105 °F, and UV indexes briefly reaching 10.

The forecast for Sunday and Monday will challenge the county record which is 96 °F for both those days. The heat may continue to the middle of next week or beyond so we’ll have to keep an eye on that.

Hottest Day and Rain Deficit Building

July 14th, 2016 (Thursday)

July 14th was the hottest day of the year at the station with the temperature peaking at 94 °F and a maximum heat index of 102 °F. This broke the old station record of 89 °F from 2006 and marked the fifth 90-degree day for the year. The heat is expected to continue well into next week with oppressive humidity and little rainfall.

We’re now at a 4.5″ rainfall deficit for the year and are down approximately 1.0″ for July. In general Berks county, especially the mid to southern portions, was in a rain “jip zone” in June. The total June precipitation was 1.48″ which is well short of the station long-term average of 5.71″.

Saturday Heat, Wind, and Summer Outlook

June 12th, 2016 (Sunday)

Saturday was the first 90 degree day at the station and therefore the hottest day of the year. The temperature peaked at 92 °F with a heat index of 97 °F and real feels in the sun over 110 °F. The Reading Airport also reached 92 °F, but this was nowhere near the record of 98 °F from 1911.

A dry frontal boundary passed the area on Sunday increasing the winds that started Saturday afternoon. Sustained winds in June are usually short-lived however Sunday’s average winds crushed the old station record. The average wind speed for Sunday was 9.5 mph which is over 2 mph higher than the old record of 7.3 mph from June 22nd, 2007.
