A Freeze Warning in effect until 10 am Tuesday for the San Joaquin Valley.
Temperatures will drop to 32-degrees or below for 5-8 hours and to 28-degrees or below for 3-5 hours.
The 28-degree mark is the critical temperature that could mean damage to farmer's crops across the San Joaquin Valley.
Tonight's cold spell won't last as long or be quite as cold as Monday morning's low temperatures.
On Monday the low temperature in Fresno was 28-degrees, Madera was 23-degrees and Hanford was 22-degrees.
The temperature was at the freezing point or below in Hanford for nine hours from just before midnight Sunday to just after sunrise Monday morning.
The valley has had freezing temperatures (and below) for each of the past four nights.
Thankfully a warming trend is in store for the rest of the week as high pressure blankets central California.
Overnight lows will climb to near normal with middle to upper 30s and low 40s and afternoon highs will be about 5-10-degrees above normal by the weekend.
