As temperatures continue to drop through the end of the week into the weekend, Saturday will bring our first 60-degree high temperature reading since May of this year. Along with that the nights will continue to drop below the 50's as well into the 40's bringing fall like weather at night.
As of 5:30 a.m. on Saturday temperatures are well into the 40'sand even low 40's in some locations. With a cold low-pressure system just to our east, this is bringing in cool northern flow aloft and near the surface helping drive these cools temperatures. Not only that but a process known as radiational cooling will occur through the nights helping temperatures drop even further.
With nights like this, where skies are clear to mostly clear, solar radiation from the day before is able to escape the surface and back into the upper atmosphere dropping temperatures near the surface. Cloud cover often acts as a "blanket" holding temperatures near the surface, but after the passage of Thursday's cold front moisture has been very low helping aid in clear skies.
This process will continue through the weekend into Saturday night and Sunday morning as we may drop down into the 40's once again. But as we go through the weekend some upper-level moisture will still be in place allowing for some cloud cover to develop through the afternoon hours this weekend. But besides that, cool and dry air from the north will continue to move over the area Saturday keeping us in the 60's. But the 60's don't look to stick around long as after another cool night Sunday will get back up into the 70's with even warmer weather looking to return.
