Make sure you pack your brolly if you're heading out in Hawke's Bay this weekend - there are showers on the way.

A Metservice spokesperson said Hawke's Bay residents should expect some bits of low cloud and drizzle on Friday.

"Then in the afternoon we're expecting showers and possible thunderstorms to develop around the ranges."

Possible thunderstorms are on the cards for Wairoa.

"There could be some downpours and some of those showers may drift toward the coast, that will be in the late afternoon or evening," a Metservice spokeperson told the Hawke's Bay Today.

On Saturday there will be some morning cloud about the region then basically a fine afternoon.

Sunday is forecast to be mainly fine and hot with a small chance of an afternoon shower.

Metservice said the showers are likely to be scattered and it will be "a mixed bag" in terms of where they hit, and how heavy they are.

Dannevirke looks like it will be the wettest of the lot, with rain on Friday and then morning rain on Saturday. The showers may return in the afternoon and evening.

Long fine spells are forecast on Sunday, but there is still the chance of a shower.

Temperatures will be coolest on Friday - 23 degrees in Napier and Hastings. But on Saturday temperatures will start climbing again.

Sunday is set to be a scorcher, Metservice forecasts a high of 27 degrees for most parts of Hawke's Bay.

The showers forecast for this weekend are the only rain that has fallen in the region since January 4.

"On the 4th and 5th of this month there were 12mm of rainfall in Napier and that's the only significant rainfall for the last couple of weeks really. So there hasn't been too much for the last few weeks," the Metservice spokesperson said.
