Unsettled conditions continue across PEI today..

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.

Watches/warnings.. None for PEI at this time.

Forecast…

Today.. Cloudy with sunny breaks, chance of showers/thundershower. Winds shifting to the NW, highs 27

Tonight. Cloudy with fog patches, very light NW winds, lows 17

Tomorrow.. Becoming sunny, light NW winds, highs 25

Sunday..Mainly sunny, light NW winds, highs 25

Monday..Mainly sunny, light SE winds, highs 25

Tuesday. Cloudy with chance of showers, light and variable winds, highs 27

Wednesday.. Clearing, light-brisk SW winds, highs 27.

Chance of showers/thundershowers later today across PEI..

Thursday July 28th 9:10am.. A weak cold front oriented basically east-west is located just north of PEI and extends from central NB through Newfoundland. This front will slowly drop southward today and be located just south of tomorrow. Showers and thundershowers will develop today as this feature crosses region giving locally heavy downpours. Tomorrow night a low pressure system will come off the US coast near Cape Cod and ripple eastward along this frontal boundary passing just south of NS. The bulk of any rain from this system is expected to stay along southern NS. Clearing skies expected on Saturday as this system pulls away and high pressure builds in. Sunday is looking the best of the weekend with lots of sunshine as high pressure dominates the region. Clouds will begin to roll in later Monday as the next system approaches. Actually this is 2 systems. A wave of low pressure will be tracking south of the Maritimes and may brush the region with some showers especially southern areas, also a cols front will be approaching from the west spreading some cloud and showers into NB by late Monday night.This front should be over the island on Tuesday and Wednesday  with cloud and showers. This backdoor front is by no means a certainty and if it down not show up then high pressure should dominate right through mid week with sunshine.

Precipitation.. Chance of showers today. Some of these could be heavy bringing local heavy downpours. The best chance today looks to be Prince county. Chance of showers continue into tonight and tomorrow across the entire island. The risk of showers ends Saturday noonish. Dry weather then expected later Saturday through Monday. Could be some showers around on Tuesday/Wednesday with the possibility of a cold front draped over the region but that far from certain.

Temperatures.. At or above normal through the period. Warmest days should be today and tomorrow.

Wind.. Light SW winds today and tomorrow shifting to North on Saturday then NW on Sunday. Westerlies for for Monday and Tuesday.

Thunderstorms.. Risk of storms later today then again tomorrow. Think the best chance for storms today will be Prince county.

Hazards.. Local heavy downpours developing later today in showers/thundershowers. Lightning activity. Today will be warm and muggy with not much wind for those working outside.

Watches/warnings.. None for PEI at this time but thunderstorm activity over NB will need to be watched today. These storms will move east over western PEI.

Forecast..

Today.. Cloudy with chance of showers/thundershowers developing, light SW winds, warm and muggy, highs 28

Tonight.. Cloudy with chance of showers, light SW winds, lows 18

Tomorrow.. Cloudy with showers and slight chance of a thundershower, light SW winds, highs 27

Unsettled conditions continue today and tomorrow across PEI..

Monday July 25th, 8:00am..  A weak north-south upper trough of low pressure remains over eastern NS this morning and is moving slowly eastward. Cloudy periods and chance of showers still exist with this system especially across eastern PEI today. Clouds will be on the increase later today as a warm front approaches front the west. The associated cold front will then quickly cross tomorrow afternoon. Showers and thundershowers will accompany these features.High pressure briefly builds in for Wednesday with some sunshine then more clouds and showers spread across the island Wednesday night into Thursday morning. This front is expected to stall over the Maritimes with unsettled weather into Friday then high pressure settles in for the weekend.

Precipitation... Well that sure was a deluge of rain across central PEI and the Montague area yesterday. 2 Thunderstorms developed yesterday and basically remained in place for a couple hours dumping the rain. Hail was also reported with both systems. I recorded just under 40 mms here in the New Haven area. I think much higher amounts occurred with the storm over Montague. At any rate, more showers possible today then again tomorrow. Again, local downpours possible. Dry for Wednesday then more rain on Thursday which may extend into Friday.. At this time the weekend is looking dry.

Temperatures.. At or above normal expected through the period.

Showers and thundershowers are once again expected to develop along this frontal boundary with some added sunshine this morning. High pressure will briefly build in later today into tomorrow morning with some clearing skies. High clouds increase later tomorrow as a warm front lifts north across the region. The associated cold front will then sweep across the island Tuesday morning. Showers and possible thundershowers will accompany this feature. High pressure builds in for Wednesday into early Thursday then a cold front crosses on Friday. Some indications are that this front will stall over the region into the weekend.

Precipitation.. Indications are that the highest rainfall amounts from yesterdays thunderstorms once again occurred over Prince county with lesser amounts over Queens. Parts of Kings county didn’t receive any. I recorded 2.6 mms here in the New Haven area. Hopefully that will change today with the best chance of showers being across eastern PEI today.

Thursday July 21st 5:30pm.. A large area of high pressure remains stalled in the Atlantic south of NS this afternoon. This feature is pumping in warm and increasing humid air from the south. Thunderstorms are expected to develop tomorrow afternoon across NB in advance of an approaching strong cold front from the west. These storms have the potential to become strong/severe and will need to be watched. The cold front is expected to sweep across the island tomorrow evening. A second cold front will then cross the island during the day on Saturday with another round of showers/thundershowers. This second front will also will also usher in cooler air for Sunday and Monday.
