The featured map presents a simple analysis of airport temperature observations from 6 PM on Sunday (23 UTC). It was a rather pleasant April afternoon with not too much wind, sunshine and temperatures shown in the 50s to lower 60s. Chillier air will start off the work week today with warmer temperatures and chances of rain by the end of the week. After lamenting if we can avoid any further winter season weather and have some spring before summer arrives by the daily features last week, it appears this week will be just that with some in-between those two seasons weather.
