Washington's Second Consecutive Top-3 Hottest June

July 1 Update: The preliminary National Weather Service monthly climate data report confirms the Washington June average temperature of 78.8°, tied for third hottest.

Original post:
Following last year's all-time hottest June, this month is closing out tied for third hottest in Washington, DC. Preliminary National Weather Service data analyzed by CapitalClimate indicates that the June 2011 average temperature of 78.8° is tied with 1943 as the third hottest June in temperature records which began 140 years ago in 1871. (Depending on rounding, the final figure may be 78.7°.)

Two out of the top 3 hottest Junes, and 3 of the top 6, have been in the last 4 years (2008, 2010, and 2011). Only 1 of the top 5 has occurred prior to 1981.

The high temperature for the month of 102° tied the all-time June temperature record. There were 10 days with temperatures of 90° or higher. Only 1 day failed to reach 80° (78° on the 14th).

Charleston's Earliest Triple Triple: First Time 3 Consecutive 100°+ Days in June

6:30 PM Update: The string of 100° temperatures was broken today, but the high of 98° at Charleston was enough to set a new record for June 22, surpassing the 97° in 1990.

Yesterday's (June 21) high has been corrected to 102°, which is a new record for the date.

2 PM Update: The high temperature today at Charleston is forecast to reach 100° for an unprecedented 4th consecutive day. The current temperature is 97°, up 2° from the previous hour.

Original post:
The Southeast Regional Climate Center(SERCC) reports that today's high of 100° at Charleston, South Carolina, tying the record [correction: see update above] set in 1990, represents the first time that there have been 3 consecutive days of 100°+ temperatures in June. The Sunday (June 19) high of 100° tied the record set in 1970, and the Monday (June 20) high of 102° broke the record of 100°, also in 1970. So far, there have been only 3 days this month which failed to reach 90° or above at Charleston.

Here are the previous Charleston 100° streaks, from the SERCC:
Rank # Days  End Date
1 7 7/14/1986
2 4 7/21/1986
3 3 8/01/1999
4 3 7/21/1942
The average temperature this month of 82.7° through yesterday is now tied with 1981 as the third hottest June and is 0.7° behind the June monthly record set last year. The Charleston data history began in 1938 at the current location, but Charleston city records are some of the oldest in the U.S., dating back to 1860.

Toasted Texas Salutes Summer Solstice;
Austin Smashes June Heat Records

Images (click to enlarge): Predicted high temperatures for southeastern Texas, June 20, 2011, from National Weather Service; 6-10 day temperature outlook, June 26-30, 2011, from NWS/Climate Prediction Center

See Record Heat for the latest updates.

Today's high of 102° at Austin/Camp Mabry fell short of the June 20 record 106°, but the summer solstice approaches shortly after noon tomorrow (June 21) with numerous heat records tied or broken so far this month in southeastern Texas. In the first 19 days of meteorological summer (June-August), 10 heat records have been tied or broken at Austin/Mabry and 11 at Austin/Bergstrom.

With an average temperature of 87.7° so far this month, Austin/Mabry is well ahead of the blistering pace set by the 86.6° in June 2009 which led to the hottest summer in 155 years of official weather records. The extended outlook indicates that above-average temperatures are likely to prevail through the end of the month.

Sunshine State on Steroids: All-Time Record High Temperature at Tallahassee

The National Weather Service reports that Wednesday's (June 15) high at Tallahassee, Florida was the all-time hottest temperature in records dating back over a century:
AT 307 PM EDT...THE TALLAHASSEE REGIONAL AIRPORT RECORDED A HIGH
TEMPERATURE OF 105 DEGREES. THIS TEMPERATURE BREAKS THE PREVIOUS ALL
TIME HIGH TEMPERATURE RECORD FOR TALLAHASSEE...WHICH WAS 104 DEGREES
SET MOST RECENTLY ON JUNE 20TH 1933. THE PERIOD OF RECORD FOR
TALLAHASSEE DATES BACK TO 1892.
The old record had also been observed on 4 other previous occasions. The previous day's high of 103° also blasted away the old record for June 14 by 4°. So far this month, daily records have also been set on June 1 (103° vs. 101° in 1927), June 3 (101° vs. 100° in 2000), and June 13 (102° vs. 101° in 2010). For the first 2 weeks of June, Tallahassee's temperature has averaged 5.8° above normal.

The high temperature of 98° at Apalachicola blasted away the previous record for June 15, set just last year, by 4°. The previous day's high of 97° also broke a daily record of 95° set last year.

Elsewhere in Florida, daily records were set at Miami (96° vs. 94° in 2010) and Gainesville (103° vs. 100° in 1977). Records were tied at Tampa (95°) and Daytona Beach (99°).

Summer 2011 Heat Records Crushing Cold Records by 13 to 1

For related record temperature posts, see: After narrowly exceeding cold records in May, U.S. heat records in the first 9 days of June have outnumbered cold records by an eye-popping ratio of 13 to 1. For the year 2011 to date, the ratio is a more modest, but still impressive, 2.2 to 1. The cumulative excess of heat records over cold records since January 2010 is over 10,000. Since March 2010 there has been only 1 month (December) with more low temperature records than high temperature records.

Although June temperatures to date have been particularly cold in California, they have been warmer than average nearly everywhere east of the Rockies.

Climate has consequences. Persistently heavy rain and flooding in the Midwest this spring has led the USDA to report today that the number of acres planted as well as harvested is expected to decrease below earlier estimates. This has resulted in Chicago corn prices reaching an all-time record high at the opening this morning (click image to play CNBC video):

Original post:
It's only the first week of meteorological summer (June-August), but high temperature records are falling by wide margins in Minnesota and southern Wisconsin.

The 103° at Minneapolis as of 3:26 pm CDT smashed the old record for June 7 in 2004 by 8°. This was also just 1° below the all-time June record of 104° set on June 27th, 1934. The National Weather Service also reports that this was:
  • The first 100°+ reading since July 31, 2006.
  • The first 103°+ reading in almost 23 years, since July 31, 1988.
  • The second earliest on record that 103° had occurred, only behind May 31, 1934.
Today's record high follows a record high yesterday (June 6) of 97°, beating the old high of 95° in both 1987 and 1979.

Other records set for June 7:
A RECORD HIGH TEMPERATURE OF 99 DEGREES WAS SET AT EAU CLAIRE WI   
TODAY AT 254 PM CDT. THIS BREAKS THE OLD RECORD OF 95 SET IN 1987.

A RECORD HIGH TEMPERATURE OF 101 DEGREES WAS SET AT ST CLOUD MN
TODAY AT 233 PM CDT. THIS BREAKS THE OLD RECORD OF 96 SET IN 2004.

RECORD HIGH TEMPERATURES HAVE BEEN SET SO FAR IN MADISON AND
MILWAUKEE (TUESDAY JUNE 7TH).

MADISON 96 (OLD RECORD 94 IN 1933)
MILWAUKEE 97 (OLD RECORD 95 IN 1933)

THIS IS ONLY THE 4TH TIME SINCE 2000 THAT MADISON HAS REACHED AT
LEAST 95 DEGREES. AND IT IS ONLY THE 5TH TIME SINCE 2000 THAT
MILWAUKEE HAS REACHED AT LEAST 97 DEGREES. THESE TEMPERATURES ARE
THE HOTTEST IN 5 YEARS.

California Rainfall Records Smashed

A strong and persistent low pressure area off the Pacific Coast brought record rainfall to the San Francisco Bay area on Saturday, June 4. The 0.66" of precipitation at San Francisco Airport was over 4 times the old record for the date of 0.16" in 1947 and 6 times the long-term average for the entire month of June. Records began at the airport location in 1927.

The 1.07" in downtown San Francisco through 6 pm was more than double the old record of 0.49" in 1939.

Although Oakland Airport observations began only in 1948, the 0.88" there swamped the old June 4 record of 0.04" in 1984.

At San Jose, where records date back over a century to 1893, the 0.88" blew away the old record of 0.18" in 1993.

Because of the persistence of the pattern, much of central and northern California has had at least 600% of normal rainfall this month to date. On the other hand, there has been virtually no precipitation east of the Sierras.

Washington Breaks Century-Plus Mark to Set Double Heat Record

Washington's high temperature of 98° on June 1 broke the more than 100-year-old record for the date of 97° in 1895. Moreover, despite the passage of a "cold" front during the evening, the midnight temperature was 83°, so the morning low of 76° also broke the daily record for highest minimum of 74° set in 1991. The 1895 record was one of only two remaining 19th-century daily high temperature records for June in Washington. The sole remaining one is now 102° on June 9, 1874.

Baltimore (BWI) also broke its 1895 record with a high of 98°.
