A very humid start to Tuesday, with a feel-like temp already over 30C despite the cloud. Here’s the dew point for 7am this morning (dew point is the temp at which dew would form as the air reaches 100% humidity – so the higher the total the wetter the air – in these charts the redder the colour the more humidity – dew point in the 20s close to the coast):

Going to feel hot and sticky today, with a decent chance of a shower or storm through the day. There were actually a decent number of storms overnight – check out this map of lightning strikes and you can see how much activity there was to our north yesterday (orange) and overnight (red):

Coming up we’ve got a strong westerly blast tomorrow. The down side? The temps will be even higher…but the upside – away from the coastal strip the humidity levels should be much lower. Here’s the 1pm forecast dewpoint for Wednesday:

You can see how the higher humidity levels are kept right on the coastal strip. Going to be HOT though – here’s the forecast temps for 1pm:

Those westerly winds however will bring a day of Very High to Severe fire danger across much of eastern NSW. Here’s the preliminary forecast for tomorrow – shaping up to be a bad fire day:

A little cooler for Thursday, though not the real cool change we’d love to see. Looking further ahead there are signs of another heatwave in the 7 to 14 day period…
