Late-July chill yields a rare summer frost advisory in Alberta
Persistent rainfall and cloud cover has cooled regions around Calgary, Alta., to well below normal. Nightly temperatures won't be much different than the daytime highs.
The best odds of temperatures hitting zero are along the Bow River, north of the Saskatchewan River and the Brazeau Reservoir area.
Temperatures are forecast to be around 0 C Tuesday overnight for parts of southern Alberta, prompting frost advisories.
While Calgary, Alta., isn't in the frost advisory, the typical, average date of the last frost is on May 21. There is a 10 per cent chance its final spring frost was on June 11, so we're in quite the rare territory.
Gardeners should take precautions to protect tender or frost-sensitive plants and trees across areas expecting near-freezing temperatures Tuesday night.
According to Environment and Climate Change Canada (ECCC), frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.
Cover your plants
But how do you protect your sensitive plans from a sneaky, late-season frost?
One key step: Cover your plants! Tarps, blankets, pots, boxes…anything you've got on hand to provide a protective bubble around your tender plants and sprouts is key to warding off the damaging effects of frost.

Wednesday Cannon Fodder: Back to School
It's a drizzly morning here in Washington, D.C., so I hope the weather is better for the rest of y'all, TSFers. I really shouldn't complain, though. At the end of spring, we planted some new trees in our backyard and the above-average rainy summer we've had has really saved my butt on the water bill (and hassle). The nursery wanted me to water them every 3-4 days — I would have been moving the hose around the yard all summer. It's back to school season. I know some are already back — our dear friend 06Nole (Tony) is one of them. My brother-in-law, who teaches in Switzerland, went back this week. My local schools go back this coming Tuesday. I know a bunch of y'all have been dropping kids off at college and grad school. Do you have any Back to School traditions or memories? Did anything funny happen this year as the (not so) little ones went off to their first day? My dad and sister would always go out for pancake breakfast the day before the school year started. Let us know in the comments! Yes, I saw the Arsenal news from today. Kai Havertz has a knee injury — prognosis and duration unclear. I'll get to it later this morning. Sigh. Solve the daily Crossword

Muggy day ahead, Maryland feels brunt of "Erin" impacts Thursday
A gloomy Wednesday morning across Maryland has slowed the morning commute with areas of mist, drizzle, and fog. The overcast and murky weather will burn off by midday leaving us with a partly sunny, warm, and muggy afternoon. A passing shower or thunderstorm is possible later today into tonight. Hurricane Erin will continue to be the big weather story today through the end of the week for Maryland and Delaware beaches with large waves, dangerous surf, and life threatening rip currents. Many beaches from Assateague Island to Rehoboth, Delaware are close indefinitely due to the dangerous ocean conditions. Tropical storm force wind gusts and rain bands in addition to the large and dangerous surf will make Thursday the toughest day of storm impacts. Wednesday morning featured plenty of gloomy weather with mist, drizzle, and fog. This will lift by midday with a warmer and muggier feel returning this afternoon. Expect highs to climb into the lower 80s with heat index values reaching the upper 80s. Expect low clouds to give way to breaks of hazy sunshine. Scattered showers and storms in western Maryland will track toward the area late this afternoon into this evening. Many of the storms will fizzle out before reaching our area, but a few isolated storms are possible this evening into tonight. This same weather system responsible for the shower chances later today and tonight will interact and help keep Hurricane Erin offshore from Maryland Thursday. Despite the center of "Erin" staying hundreds of miles offshore, we'll still be dealing with fringe impacts from the storm. Breezy weather is to be expected across most of central Maryland Thursday along with a few waves of scattered showers. The best chance of showers will be during the morning, midday, and early afternoon hours. While Thursday looks breezy across central Maryland, disruptive winds are not likely in Baltimore and points west. Expect northeast winds at 10 to 25 mph with gusts to 25 mph. Closer to Chesapeake Bay, winds will ramp up just a bit with gusts 30 to 35 mph, so localized bridge and travel restrictions are possible, but even these impacts look minimal. In addition to some windier weather along the Bay, minor coastal flooding still could be an issue with high tide cycles later today through Thursday. Maryland and Delaware Atlantic Ocean beach communities will feel the brunt of "Erin" impacts today through Saturday. The greatest concern right now is life threatening rip currents continuing through at least Friday. Many beaches including Ocean City, MD, Assateague Island, and Rehoboth Beach, Delaware are closed indefinitely to swimming due to the extremely dangerous conditions. High Surf Advisories are in effect for the entire Maryland and Delaware coastlines for large and dangerous breaking waves reaching 8 to 12 feet later today. These sets of waves will continue to create life threatening rip currents and areas of coastal flooding. This will continue through at least Friday. Tropical Storm Warnings are in effect for the adjacent waters of Maryland and Delaware for winds gusting 40 to 55 mph. Wind gusts at many Atlantic beaches in Maryland and Delaware will reach 35 to 45 mph Thursday, especially late morning through early evening. Rain bands may also accompany the wind from time to time. The worst impacts from "Erin" in terms of wind and scattered showers will quickly end Thursday evening, but the ocean will remain extremely rough despite the storm's exit. Rough surf, dangerous rip currents will likely continue Friday and Saturday despite some beautiful weather. Please only swim at beaches with lifeguards on duty and obey all of their instructions. Friday and Saturday will be supreme weather days with plenty of sunshine, comfortably warm temperatures, and dry weather. Highs will top out in the lower to middle 80s. Sunday should stay dry, sunny, and warm through late afternoon. This should lead to another pretty nice outdoor day, but you'll need to keep an eye to the sky for some late day gusty storms. These storms will slowly cross the area Sunday night and exit Monday. Another batch of fall-like air is likely next week just in time for the kids returning back to school.

Cooler temperatures and stray showers move into the Pittsburgh area on Wednesday
After a hot and dry day on Tuesday, a weak trough of low pressure and its associated cold front are moving into western Pennsylvania this morning, bringing us some scattered to numerous showers. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos High-res model guidance is generally favoring areas from the Pittsburgh metro and points north and east with the best chance of showers this morning through 1-2 p.m., then some isolated activity in the Laurel Highlands as well. The cold front with this system is going to dissolve over the region tonight into Thursday. As winds still converge along this boundary, we will keep stray to isolated chances of precipitation in place through Thursday afternoon. Some patchy dense fog is also likely on Thursday morning. By Friday, high pressure moves in, leading to clearer skies across the region, which will lead into a short-lived warming trend this weekend. High temperatures on Friday will reach the mid-80s, then upper 80s to near 90 are expected as southwest winds increase ahead of another stronger trough of low pressure and approaching cold front. This will bring a chance of some isolated afternoon and mostly evening storms Saturday into the predawn hours of Sunday. As a second stronger trough embedded within the flow moves in Sunday night into Monday, there will be additional scattered showers and storms, followed by a strong cold front that will give us a preview of fall for early next week. Below-average temperatures are expected from early into the middle of next week! Stay up to date with the KDKA Mobile App – which you can download here!
