Friday July 29th 9:40am... That was quite a night.. Storm chasing yesterday took me to west Prince (West Point and Howards Cove) where I watched the first wave of thunderstorms roll in from NB. Headed back towards Charlottetown mid evening and drove through Extremely heavy rain all the way to Summerside. Got home here in the New Haven area by 9:00pm just as the rain was beginning from new storms developing over Queens county. Thunder and lightning with heavy rain til midnight.
A stalled or very slow moving cold front oriented NE-SE is draped across western PEI this morning. Showers and thundershowers developed yesterday late afternoon ahead of the front and continued through the night. The front will eventually move off the coast of NS tonight taking the showers with it. A couple will take place tomorrow. First, high pressure will begin to build in from the west behind the front and should give some sunshine and seasonal temps to the island but at the same time a low pressure system off Cape Hattaras will track NE along this stalled frontal boundary and is expected to pass south of NS. The associated weather from this low will most likely be confined to southern NS. High pressure should dominate the weather picture into Monday then a weak frontal system is expected to spread some cloud and showers across the region on Tuesday into Wednesday. High pressure returns for later Wednesday into Thursday.
Precipitation.. I recorded 10.6 mms rain past 12 hours but many areas recorded much more. Charlottetown recorded over 20mms. Chance of showers again today ending tonight. Dry for tomorrow through Monday. Chance of showers again on Tuesday then dry for later Wednesday into Thursday.
Temperatures.. At or slightly above normal through the period.
Wind.. Will shift to the NW behind the front first up west then down east late tonight. Light NW winds should continue for tomorrow and Sunday shifting to SE on Monday and Tuesday. Light-brisk SW wind develops for Wednesday and Thursday.
Thunderstorms.. Still a slight chance of storms today especially of we get some heat and sunshine. The best chance of storms would be across eastern half of the island. The next chance then appears to be Wednesday of next week.
Hazards.local downpours later today across eastern PEI. Possible thunderstorm activity. eastern half of the island.
