NORMAN — Summer 2013’s mild temperatures may hit record lows this week as a system of low atmospheric pressure known to meteorologists as an “upper low” or “trough” will make its way across the state Sunday.
National Weather Service meteorologists posting forecast discussion on the NWS website commented, “Given the past few summers around here...we will take it.”
Record daytime lows in the upper 70s and lower 80s have been predicted for Sunday and Monday, with high chances of rainfall likely during the day Sunday and Monday, particularly in central and southern Oklahoma.
NWS meteorologists also have predicted deep layer fog in the I-35 corridor Sunday morning, calling for caution while driving.
Temperatures are predicted to climb back to low to mid 90s for the latter half of the week.
