Lows in some areas dropped into the mid 30s this morning, allowing for some patchy frost. Frost occurs even when thermometers read 33-36°. The reason is that thermometers that take air temperature are placed a few feet above the ground. On a clear & calm night, cooler air sinks and falls to the ground. This allows the temperature at grass/plant level to be around 32°, even though your thermometer might read a little higher.
One good thing about very dry air this time of year is that it warms quickly. Highs will reach the mid 60s today. A bigger warm-up is slated for next week.
