Scattered to numerous storms expected today for the Pittsburgh area
It's going to be another day with scattered to numerous storms expected today across the Pittsburgh area. First Alert: None Yesterday was our 10th 90-degree day of the year as temperatures managed to briefly spike up in between waves of thunderstorms during the early afternoon. This morning begins much like the last several across our area with temperatures struggling to drop below 70-degrees amid very humid conditions. As expected, these storms produced very heavy rain in spots with localized swaths of 2-3"+ although a majority of folks did not receive this. There were multiple reports of flash flooding in Central to Southern Washington county. A stationary front is gradually dissolving over the region with additional waves of energy aloft in the atmosphere pivoting in from the northwest. This will support a continued opportunity for rain and thunderstorms through early evening. Atmospheric moisture levels remain unusually high across our area, so any of these cells will be able to produce heavy rainfall rates in a short amount of time. As a matter of fact, there is a good chance that when the morning weather balloon is launched, we will likely break a record for the amount of moisture in the air. The peak of t-storm coverage won't occur until midday through early afternoon. Once the trough passes to our southeast, expect storms to shift south of I-70 by 6-7pm and exit our area for the most part between sunset and midnight. With high relative humidity, clearing skies, and light winds, much of the area should see dense Monday morning. This fog will begin to mix out by midday to early afternoon with partly cloudy skies and hot conditions. Air temperatures Monday through Wednesday will likely reach 90 degrees with heat indices in the mid to upper 90s. As far as storm chances go, these will highly depend on when spokes of lift from disturbances called shortwaves pivot into the area. The core of the heat ridge will be centered across the Midwest and Mississippi River Valley Monday-Wednesday. A weak shortwave will move into the area late Monday evening. This may trigger a stray to isolated storm chance Monday evening in our westernmost counties. Another wave may move in on Tuesday evening with strong storms more likely into portions of Central OH, but if these survive the trip, we may take part in that activity as well. The day most likely to see storms this week will be between Wednesday evening into midday Thursday as a stronger cold front moves through. Some storms could briefly turn severe Wednesday afternoon with remnant showers on Thursday. Substantially drier air and slightly below normal temperatures are expected to end the week.

Hot weather in NYC on Saturday as more storms approach. Here's the First Alert Forecast.
After Friday's heat and strong storms, we're in much better shape weatherwise today in New York, New Jersey and Connecticut. Expect a mix of sun and clouds with temperatures climbing into the mid 80s Saturday. Humidity will be gradually falling, so it will feel close to the actual air temperature. Tonight, clouds increase and there is a chance of a shower or two after midnight. Lows will be in the upper 60s and low 70s. Sunday is our next First Alert Weather Day. There will be plenty of clouds with rounds of showers and storms throughout the day tomorrow. Humidity spikes again, too, so any downpours will be capable of brief heavy rain. Localized spots of flash flooding are certainly possible wherever the heaviest cells move through. Additionally, there is a marginal severe weather risk for the late afternoon and early evening hours. The best chance of some stronger storms will be southwest of New York City. While not a complete washout, try to have alternative plans in place. After sunset, things quiet down before our next round of heat. Heat indices early next week will likely exceed 100 with highs back into the low and mid 90s. Tuesday looks like the day for peak heat. Then, some more storm chances likely move in ahead of a cold front by midweek.

Pair of Alert Days for Heat and Storms this Weekend
Welcome to the weekend! As we're going into the final days of July, it'll certainly feel like summer across Maryland. High temperatures will peak in the low 90s, which isn't out of the ordinary for this time of year however, as we've said many times this summer so far, the humidity will make the heat so much worse. Continued elevated humidity combined with 90+° temperatures AND a chance for stronger storms have today and Sunday marked as WJZ First Alert Weather days. Feels like temperatures approach (and some areas will feel over) 100° during the afternoons on both Saturday and Sunday. As you may expect on a July afternoon, we also have potential for storms to develop. A warm front will be moving in today and briefly stall nearby, keeping the chance for storms for Sunday. Isolated storms could be severe with damaging winds as the main severe threat. Any showers could also produce heavy rainfall. Once the front moves out, the weather quiets down for a couple of days. The temperatures will stay on the warm side and humidity stays high, as well. A mid- to late week cold front fires off a few storms on Wednesday and Thursday before more quiet weather for the end of the week. There will be a difference with the later set of drier days . . . temperatures and humidity both appear to drop substantially. The first few days of August appear to be comfortable with highs running below normal. Hang on for just a few days as better weather is on the way. The First Alert weather team will be keeping you updated every step of the way.

Periods of storms expected this weekend throughout the Pittsburgh area
It's going to be a hot and humid weekend with periods of storms expected to move through the Pittsburgh area. First Alert: None at the moment WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos Temperatures once again have struggled to drop below 70 degrees in Pittsburgh early Saturday morning as we are in the midst of an unseasonably warm and very humid air mass. Presently, we are at 18 days this year with a low temperature of 70 degrees or higher, and there is a good chance we could be in second place for the greatest number of 70-degree warm mornings on record at Pittsburgh International Airport by the middle of next week. Our large scale weather pattern this weekend will be comprised of continuous heat and humidity accompanied by periods of storms. A frontal boundary has stalled out across our area and will likely meander between the I-70 to I-80 corridors with strong and deep moisture convergence near the boundary. Several impulses aloft in the atmosphere will be moving atop this boundary bringing periods of storms as they pass through. The first of which will move across our area between sunrise and noon today. There will likely be a break in the thunderstorm activity by early to mid afternoon before the next disturbance moves in with increasing shower and storm chances this evening. Temperatures will rise from the lower reach the mid 80s for most by early afternoon. Storms may produce microbursts with wind gusts peaking around 40-60 mph and isolated instances of pea to dime sized hail. Heavy rai and flash flooding will also be a threat with isolated amounts of 2-3" in areas that see repeated storms, but a majority of folks will see around 0.5". Additional showers and storms are likely overnight as waves of energy pass through. The overall coverage will decrease some with areas mainly north and east of Pittsburgh being favored hotspots for storms. Temperatures will be very warm as well as lows struggle to drop below the low-mid 70s for most. Sunday morning will begin with mostly cloudy skies and a few isolated showers, but it is likely that storm chances will ramp up pretty early in the day—likely before noon as the ground temperature needed to initiate storms will only be in the upper 70s to low 80s. Storm coverage will start to decrease and shift south of Pittsburgh by early evening with clearing skies and areas of fog by Monday morning. Next week, a series of disturbances rotating around the heat dome parked to our southwest will move our way bringing isolated periodic storm chances. Timing is still fluid with this activity but keep an eye out Monday evening through Tuesday morning. A stronger cold front is expected to arrive around July 30-31 which will bring near to slightly below normal temperatures accompanied by drier air to our region.
