This combined with multiple days of near record breaking temperatures will exacerbate the impacts from the heat and humidity. The hottest conditions are expected to occur through today, however dangerous heat will continue through Saturday. ISSUED AT Friday, July 3, 2026 at 1:40 PM EDT ISSUED BY National Weather Service Mount Holly NJ HEADER URGENT - WEATHER MESSAGE # PRECAUTIONARY/PREPAREDNESS ACTIONS -------------------- Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1. If you do not have air conditioning in your home or lack shelter, you can call 211 or visit your county or state health department website for assistance locating appropriate shelter from the heat. # AREAS AFFECTED -------------------- Berks, Hunterdon, Lehigh, Morris, Northampton, Sussex, Upper Bucks, Warren, Western Chester, Western Montgomery Including the cities of Newton, Washington, Honey Brook, Reading, Pottstown, Chalfont, Perkasie, Oxford, Flemington, Collegeville, Bethlehem, Morristown, Allentown, and Easton
Lightning Alert
-Closest strike: 8.49 miles Stay Alert! Remain in a safe area until there has been no lightning within 10 miles of this location for 30 minutes. Please be aware that lightning activity can remain high even when a storm is moving away from your location. Even if rain has stopped, do not leave your safe area until WeatherBug indicates that lightning is more than 10 miles away from this selected location. IF OUTDOORS Avoid water, high ground, and open spaces. Avoid all metal objects including electric wires, fences, and machinery. Find a safe area in a building or in a fully enclosed vehicle with the windows completely shut. Unsafe places include underneath canopies, small picnic or rain shelters, convertibles, or near trees. IF INDOORS Avoid water and stay away from doors and windows. Avoid using a hard line telephone. Take off headphones. Turn off, unplug, and stay away from appliances, computers, power tools, and TV sets. Lightning may strike exterior electric and phone lines, inducing shocks to inside equipment.
Severe Storm Risk
-There is a Slight Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF EASTERN NEBRASKA INTO WESTERN IOWA AND SOUTHERN LOWER MICHIGAN SUMMARY A swath of damaging to severe gusts is expected across southern Lower Michigan over the next few hours. Scattered damaging gusts are also likely over portions of the Mid Atlantic. Otherwise, scattered wind damage and large hail are still expected from parts of Nebraska into Iowa today. Isolated to scattered severe storms remain possible extending eastward from the northern/central Plains into the Midwest and Tennessee Valley. 20Z Update The main change made to this outlook was to upgrade southern Lower MI to a Category 3/Enhanced Risk, driven by 30 percent/CIG1 wind probabilities. A cold-pool-driven MCS, with some bowing tendencies and a history of producing numerous measured gusts in the 60-70 mph, is rapidly approaching southern Lower MI. KGRR inbound velocity data shows a rear-inflow jet exists with this MCS, and surface observations/latest mesoanalysis show a favorable environment in place for bow-echo persistence. Surface temperatures are exceeding 90 F in spots, amid 70-75 F surface dewpoints, yielding a gradient of 1500-3500 J/kg MLCAPE. Up to 30 kts of effective bulk shear coincides with this buoyancy gradient, with vectors oriented normal to the MCS leading-line orientation. Therefore, the expectation is for a damaging wind swath to occur over southern Lower MI with the passage of this MCS. At least scattered gusts will likely exceed 50 kts in intensity, and a few of these gusts may exceed 75 mph. 30 percent wind-driven probabilities were also added over portions of eastern PA into far southeastern NY and NJ, where surface temperatures are exceeding 100 F in spots ahead of a developing multicellular cluster. While vertical wind shear is modest, the well-mixed boundary layer is yielding low-level lapse rates well over 8 C/km on a widespread basis, with corresponding DCAPE approaching 1500 J/kg. As such, several of the stronger storm cores may produce wet downbursts capable of at least tree/wire damage on a scattered basis, and a few severe gusts are also possible. Otherwise, the previous forecast (see below) remains on track.
