Meteorologically, high pressure occurs in between areas of low pressure. These low pressure systems are associated with inclement weather whereas high pressure is associated with fair weather or clear conditions.
As the wide range of daytime highs and overnight lows varies as much as 30°F, some wonder if this El Nino year could be more severe than once predicted.
Tonight another evening of 30°F lows after an impressive day of heating up to the low 60s. Tomorrow an even warmer day as southerly flow brings in more moisture, trapping more heat during the day, keeping things in the 50s during the night by the end of the week.
