Current Observations: Spring/Summer 2021


Recommended Posts

Phoenix had a preliminary low temperature of 92°. That would easily surpass the existing record high minimum temperature of 88°, which was set in 2008. That would be the earliest 92° minimum temperature on record. The existing record was set on June 25, 2017. It would also be the 3rd consecutive 90° low temperature and the first 3-day stretch entirely in June. The earliest such streak occurred during June 29-July 1, 2013.

 

Death Valley had a preliminary low temperature of 101°. That would smash the existing mark of 94°, which was set in 1961.

Morning thoughts...

 

Today will be partly cloudy and very warm. Temperatures will likely reach the upper 80s and even lower 90s in most places. A shower or thundershower is possible, especially during the afternoon or evening. Likely high temperatures around the region include:

 

New York City (Central Park): 88°

Newark: 93°

Philadelphia: 89°

 

Normals:

New York City: 30-Year: 80.8°; 15-Year: 80.6°

Newark: 30-Year: 83.1°; 15-Year: 83.1°

Philadelphia: 30-Year: 84.4°; 15-Year: 84.6°

 

Tomorrow will be another very warm day. 

 

Out West, record-breaking heat will continue across the Southwest, including Phoenix. Phoenix will likely record its record-breaking 5th consecutive day with temperatures reaching 115° or above.

 

Daily Records for June 19:

 

Phoenix: 118°, 2016 and 2017 (Forecast: 114° to 118°) 

Tucson: 115°, 2016 and 2017 (Forecast: 110° to 114°)

 

*-Forecast range is 1 sigma below and above the forecast mean.

At Phoenix, the preliminary low temperature was 91°. That would break the existing record highest minimum temperature for June 19, which is 86°. That record was set in 1958 and tied in 1959. Today's preliminary figure would also be the 4th consecutive minimum temperature of 90° or above. That would further extend this year's June record and would be the earliest 4 consecutive-day stretch on record.  The existing record was set during July 8-11, 2020, the opening part of a all-time record-tying 7 consecutive days. The historically-hot summer of 2020 would go on to have a second 7-day stretch.


2020 saw a record 28 such days, which smashed the old record of 15 such days, which was set in 2003 and tied in 2013. Prior to 1934, Phoenix had never had such a high minimum temperature. It now averages 7.4 per year (1991-2020 climate period), which is up from 4.1 per year during the preceding climate period.
