Tropical Storm Colin

Posted in Tropical Weather, Weather News at 11:05 am by Rebekah

Tropical Storm Colin formed out over the Atlantic this morning, but is not expected to become a hurricane and is unlikely to pose any threat to land, aside from possibly a few of the Leeward Islands.

Colin is a new addition to the Atlantic storms name list, as Charley was retired following the 2004 hurricane season.

Russian Heat (Yet Again!)

Posted in Non-US Weather, Weather News at 8:17 am by Rebekah

As a follow-up to this past week’s posts on the heat wave in western Russia, here is a plot of the temperature anomaly for July 29th, Moscow’s hottest day on record.

Note that the average temperature for Moscow on this day was 10 to 12 °C (18 to 22 °F) higher than the climatological average temperature for July 29th.

Although temperatures have since cooled down a few degrees, Russia is still under a massive ridge.  This ridge will continue to build through at least the end of this week, when temperatures in Moscow could reach 100 °F or greater (possibly breaking the new record yet again).
