Good afternoon, Foothills Weather Nation. What an amazing day it is outside! As Daniel mentioned in his post two days ago, our clear skies will be interrupted by a bout of precipitation tonight into the morning hours tomorrow as a cold front associated with a short wave trough propagates into the area.
Let's talk about the timeline of what we can expect tonight on through Tuesday as our cold front is expect to bring along with it some below average temperatures for the region and the start of April.
Clouds will continue to fill in as we progress on through the evtening and we are expecting the rain to start after midnight at around 1-2 am. With the warmer day and the heat blanket effect we won't see our overnight temperatures drop much- only down to the mid 50's across the region, but this overnight low will be near the high that we expect for Sunday. Total accumulation from this front is around a tenth of an inch with potentially higher amounts in localized areas and minimal to no threat of lightning. The rain is expected to stop completely before noon Sunday.
Below is a screenshot from the NWS of the hourly forecast showing the steady temperature decline from Saturday night on through Monday morning.
Sunday afternoon - Monday night
Sunday afternoon we will hit our peak temperatures in the mid to upper 50's clearing to clear skies as we go into the evening hours. Drier air will fill in behind the exiting of the front which will allow for overnight temperatures to have a relatively significant drop into the low 30's. Ultimately we are seeing a 40-45 degree temperature drop from today's high to Sunday into Monday overnight low. Monday day will be in the low to mid 50's, mostly clear skies, and a mild easterly wind. Cloud coverage will increase again as we progress into Monday evening. Overnight low Monday into Tuesday in the mid 30's.
Tuesday - Tuesday night
For our last bit of our forecast we are seeing a little jump in precipitation probabilities as a weaker shortwave trough sweeps through the region. Temperature wise we are seeing similar values for daily highs and nightly lows as we will see on Monday- maybe a couple of degrees higher. Cloud coverage will be party sunny, precipitation probabilities currently around 30 percent, and possible rainfall totals for Tuesday around .03 inches regionally. The bulk of the precipitation is expected to be between 10 am and 6 pm, so mainly gone and skies beginning to clear out as we go into Tuesday night.
Once we see the sunshine again on Wednesday morning we will be out of our cool trend and onto warmer, more seasonal days for the rest of our work week.
I hope you have a great rest of your weekend! Thank you for reading!
