Mother Nature is bringing us absolutely glorious weather for this Easter Sunday! Highs this afternoon will easily reach the middle 70s under partly sunny skies. A developing area of low pressure across Indiana will surge northeast tonight and pull a cold front into our area this evening. This means that while the weather will be great all afternoon, there will be a risk for storms this evening.
As moisture increasing this afternoon, a pop up shower or storm cannot be ruled out between 6 p.m. and 9 p.m. however they should remain isolated. The cold front to our west will bring a broken line of thunderstorms into the metro between 10 p.m. and midnight this evening. With highs in the 70s today, we are building up a decent amount of instability (energy for storms) in the atmosphere. However, temperatures will cool off slightly into the 60s this evening. The combination of leftover weak instability and moderate wind shear ahead of the front will mean some isolated stronger storms will be possible. The main threat will be for a few damaging wind gusts. Due to the loss of daytime heating though, the threat looks marginal and isolated; certainly not widespread.
The front will clear our area around or just after midnight bringing an end to the threat for thunderstorms. A few showers may persist for a couple hours and winds will pick up as well with gusts to 35 mph likely overnight.
You will wake up to much cooler weather on Monday morning. Lows are expected to drop into the lower 40s overnight. Skies will be mostly cloudy throughout the day prohibiting much of a warm up. Expect a high temperature in the low to middle 50s. Breezy west-northwest winds will gust between 20-25 mph as well.
If you have any plants sensitive to the cold, you may need to cover them up Monday night. We will likely drop to near freezing come Tuesday morning. Sunshine will warm us up quickly through the day though with highs reaching the upper 50s. Patchy frost is possible Tuesday night as we drop into the middle 30s but a southerly breeze will develop just before sunrise which should keep us above freezing.
We will head back to nearly 70 degrees on Wednesday as a strong area of low pressure to the west draws up warmer air from the south. A few scattered showers are also possible mainly after sunset.
Rain and thunderstorms will be likely on Thursday as that area of low pressure moves by. This will cause another cold front to swing through making our warm up only brief once again.
Cooler air filters in for the end of the week and next weekend. In fact, an even stronger cold front may cross the region next weekend bringing a serious chill to the region for the first few days of April.
We are definitely not done with freezing temperatures yet as they will likely occur this week and next week. The EPO (Eastern Pacific Oscillation) is taking a major dive this week which means a large ridge of high pressure in the upper atmosphere will develop over Alaska and northwestern Canada. This ridge will cause a flow straight out of the north which will bring us the cold next weekend. The pattern will not disappear rapidly but there are some signs that it relaxes by the 2nd or 3rd week of April. As is typical for spring, there will be some warm ups in between the cold air shots (like this week).
