Incoming weekend storms to bring cooler 70s and scattered rain

You're watching the Fox 10 Weather Experts with meteorologist Erica Horvathin on Fox 10 News. Welcome back. It is a gorgeous evening out there. Look at that sunset. It is shaping up to be so pretty tonight. Temperatures are still in those low 80s and today we had a high of 84 degrees, which was just a degree warmer than the past few days. Still about five degrees above average for our high and well above average for our morning low as well. We're only going to be warmer than normal, though, for really one or two more days before temperatures will drop. Back off below average into the 70s in the valley. Right now we're at 82 degrees in Phoenix, 66 in Sedona, 54 in Show Low, and 53 in Flagstaff. And here's how things are going for the rest of this evening. Clear skies, light winds, temperatures falling through the upper 70s. Doesn't get much better than that here in the valley. We still do have the influence of high pressure, which is keeping our weather nice through tomorrow. That means skies are staying sunny and temperatures are staying low. Temperatures will be a degree or so warmer than today. It'll be our warmest day of the week, and then we'll be waiting for this storm system here to bring in some cooler temperatures and rain as we go into our weekend. But here's how tonight looks across the state. Freezing temperatures in at least a few spots up north. Flagstaff, winds low, coming close in Show Low. 48 tonight in Sedona and 37 in Flagstaff. We'll see 62 in Phoenix and 53 in Casa Grande. Monday, tomorrow afternoon, there is that. That slight warm up I was mentioning with 50s, 60s and a low 70s in the high country and mid 80s across the deserts as high as 87 in spots like Gila Bend. Now the next storm system will swing in here Friday to Saturday. This is going to be coming in from the south. So it's a warm core system. It's not going to bring too much of a cool down. The only reason we'll really cool down Friday. from this system is because of some increasing clouds and a chance for rain. Most of that rain looks to arrive during the evening and overnight, and it stays primarily in the southern half of the state, other than some isolated mountain showers that could venture a little further north. And by Saturday, a second system is going to swing in through the northern state line in southern Utah. This will bring rain to the northern half of the state and some much cooler air, including temperatures in the low to mid-70s for the valley. So with that first system, rainfall accumulation is looking very, very light as you can see here. This is Friday at 5 p.m. We see better chances Friday night through Saturday morning. And then that second storm will bump those totals up a little bit in central and northern Arizona. But this is not like the storms that we have seen over the past few weekends. This is going to bring... Relatively low rainfall amounts, meaning we're not dealing with as high of a flooding threat from these storms, but it'll bring some wetting rainfall here and there, especially in the mountain terrain. We'll see a 10% chance of a shower possible Friday evening, but most rain will arrive in the valley Friday night with a 30% chance of rain then. And that will continue into Saturday. But by Saturday night and Sunday, we're going to be dry. So hopefully that helps you plan out your weekend. Here's our 10-day forecast. And our temperatures are dropping into the low 80s by Friday and mid-70s on Saturday. And we'll stay in the 70s through next week with another storm possible on Tuesday.
