Drying Out Through the Weekend

Isolated showers continued today for the morning hours, but many locations saw dry conditions and blue skies heading into the weekend.  Although spotty showers are possible in a few places overnight,  most will see partly cloudy skies.  A warming trend will begin this weekend with temperatures spiking by Tuesday.

Currently, the flow in the mid-levels of the atmosphere (about 18,000 ft.) is what we call zonal.  That means that the winds are blowing west to east, without much turning towards the north or south.  Winds at this level help steer storm systems around the globe.  Typically when the atmosphere is in this state, no big changes take place in the weather pattern.  The zonal flow that we are seeing will only continue for a few more days, until a ridge of high pressure moves into the Northwest.

This ridging brings the heat back to southern Oregon and northern California.  Temperatures Monday and Tuesday will be well above average, and for many locations, close to records.  The Rogue Valley and northern California will climb to near 100, but other locations will still highs warmer than the seasonal normal.
