SYNOPSIS
High pressure will continue to bring well above normal temperatures and dry weather to the region into next week.
DISCUSSION
For today, an anomalously strong high pressure system will remain in place across northern Arizona, leading to another round of dry weather and near record warmth. High temperatures are expected to be between 10-20 degrees above average. Yesterday, a high temperature of 68 degrees was observed at the Flagstaff Airport. This tied the daily record set in 1950. Flagstaff may tie or break today's daily high temperature record of 64, set all the way back in 1921.
This unusually strong high pressure system will largely dominate northern Arizona's weather through next week, with fair weather and near record warmth forecast to continue. On Sunday and Monday, high temperatures may dip a couple of degrees due to passing high clouds and influences associated with a weak shortwave trough forecast to overtop the ridge. Otherwise, light winds are forecast through Tuesday. On Wednesday, the ridge flattens, resulting in breezier southwest winds with speeds in the 10-20 mph range.
