Heat advisory in place today for the Pittsburgh area
A heat advisory in place today for the Pittsburgh area with temperatures expected to reach the 90s with heat indexes in the 100s. Any Alert Days Ahead? Due to the Heat Advisory issued by the NWS we have made today a First Alert Weather Day. Could potentially have another one in place Wednesday. Aware: From June 1 through July 27th, we have spent the 4th most time on record with temperatures at or above 75°. This has been a hot summer. No matter how you look at it, this summer has been a hot one. Data continues to show what we already know. The one I pulled yesterday was just how long we have seen temperatures at or above 75 degrees so far this 'summer'. For the stats, I pulled data from June 1 through this past Sunday, July 27th. Data shows that we stand at number 4 on the list of 'hottest' based on this, with a total of 658 hours spent at or above 75°. Last year, over the same span, we spent 706 total hours at or above 75°. For people who don't have a/c units, 75° is a good cutoff when it comes to the body's ability to cool down and recover from hot weather. It is also a good way of looking at how humid it has been over long stretches, with warmer temperatures happening when humidity levels are higher. Highs today should hit the low 90s. There is a heat advisory in place for Pittsburgh and surrounding areas through 8 this evening. Heat index values should hit triple digits. A heat advisory is issued for our area when the heat index value is expected to be between 100° - 105°. That's the case for today. We may also have a heat advisory issued on Wednesday with a set-up similar to today. I have Wednesday's high temperature also hitting the low 90s with high humidity levels. Interestingly, NOAA's Storm Prediction Center has us in a marginal risk for storms on Wednesday. Relief from the heat comes on Thursday with a cool front passing us by. Most of Thursday will still be humid, but I have highs not hitting the 80s. That to me may change. I am actually surprised that data shows us just in the 70s for the day. I have almost bumped up temperatures already, but will wait another day before bumping those highs up. To me, we should still have a hot airmass in places through at least noon. We will see more cloud cover, but it shouldn't take much to see highs in the 80s ahead of afternoon rain. Rain and storms will be strong and maybe severe as the cold front sweeps through. Behind the front, we will see more comfy air in place with highs in the upper 70s both Friday and Saturday. Low humidity values will make it comfy through at least next Tuesday.

Cooling begins Tuesday in Minnesota ahead of quiet stretch
Minnesota is headed for a much-needed break from the intense heat and humidity. Expect highs in the lower 80s on Tuesday with moderate dew points, which will drop by night. Then, winds turn breezy from the northwest, helping usher in cooler, drier air. Some wildfire smoke may also mix in, especially up north. An air quality alert is in effect for the northern half of the state through 11 p.m. on Wednesday. A few isolated showers or weak storms are possible later on, mainly in southern Minnesota during the afternoon and overnight hours. A quiet, pleasant stretch begins midweek, with sunshine and highs in the upper 70s through Friday.

Iona strengthens to Category 3 hurricane in central Pacific off southern Hawaii
HONOLULU (AP) — Iona strengthened to a Category 3 hurricane several hundred miles south-southeast of Hawaii, but poses no threat to the islands, the U.S. National Hurricane Center said Tuesday. Iona is one of two major weather systems in the central Pacific Ocean. In its latest advisory, the Miami-based center said Iona was about 790 miles (1,271 kilometers) off Honolulu, with maximum sustained winds near 115 mph (185 km/h). Additional strengthening is forecast later on Tuesday, with steady weakening expected to begin by Wednesday. Hurricane Iona is the first named storm of the hurricane season in the central Pacific and emerged Sunday from a tropical depression. It continues to trek west over warm, open waters. No coastal watches or warnings were in effect. Meanwhile, Tropical Storm Keli is further south with maximum sustained winds of 40 mph (65 kph). It was about 960 miles (1,550 kilometers) southeast of Honolulu and was moving west at about 12 mph (19 kph). The administrator of the Hawaii Emergency Management Agency on Monday hosted a statewide conference call with all counties, during which the National Weather Service provided an assessment and status of the storms. 'All counties are monitoring,' agency spokesperson Kiele Amundson said in an email. Another indirect impact from the weather systems could be swells, but they are relatively small and moving westward and won't create anything significant, said Derek Wroe with the National Weather Service in Honolulu.. However, a large swell is headed toward Hawaii after being generated several hundred miles east of New Zealand. It's expected to arrive in Hawaii by Thursday, about the same time the storms pass the state. 'People might wrongly attribute the swell energy to be from these tropical systems, but they're actually not,' he said.
