If the forecasters are to be believed, there will be thunder in East Anglia before the day is out.
How about this for logic?
Yesterday, our Maplin weather station lit up like a Christmas tree and began bleeping. ( It has been indicating low battery for months 
So, if the battery is not flat, it soon will be!
Finally fitted new batteries. NOTHING. After several attempts, noticed that as the batteries were shaken out there was an split second green light. Loose connection? Took apart (Nothing to lose )
After several examinations with a high power magnifier, spotted a hole in the solder on one of the battery connections. Resoldered all six connections, reassembled, fit batteries and Whoopee did all the right "start up" signals. Went through the set up procedure and awaited results.
Wonder how it has survived new batteries being fitted over the years!
It now shows 35C under the kitchen window cill (solar gain ) and 30 C in the shade in the kitchen.
Some rain (not too heavy ) to lower temperatures and save watering the garden, will be welcome.
