I am making this thread international since Latvia may see convection rivaling mid-July 2001's sounding measurements, per GFS.

This forum is now under moderate level users weather watch, what may be upgrated to High level users weather watch tomorrow. All visitors who live in Estonia, Latvia or in neighboring countries and expect thunderstorms that time are encouraged to register and post your observations here.

Here in Laguja, cumuluses are firing up and air temperature is 19,3 degrees Celsius

I have started to detect lightnings from AM radio. Some darker clouds at the westerly directions. Strong radar echoes and thunderstorms in Latvia

Latvian weather radar is now indicating rain area with intensity more than 10 mm/h west from me. It might be headed to my neck of the woods. I am indeed seeing darker cloudiness in the west and it is rather dim outside. Air temperature is 17,0 degrees Celsius.

Latest GFS run has shifted biggest convection more southward, but Laguja area might still have 568 J/Kg CAPE and -1 degree LI.

Although I went to sleep last evening, I decided to wake up in every 2 hours to check the weather. Now at 2 AM check time, I found that a thunderstorm has formed in Latvia and might be headed towards me. I think I see some distant lightnings in SW, but I am not sure. AM radio is full of thunderstorm signals. At the moment, air temperature is 14,1 degrees Celsius

I am seeing some distant lightnings... Just now I saw 3 in a row due south. Whoa... Air temperatur 14,6 degrees. It is one and a half hour until sunrise, but daylight should start appear within a hour... Good... I prefer daytime thunder to night time...
