This afternoon there will be plenty of sunshine throughout the country.
Temperatures are expected to reach highs of 27 deg C, 81 in Fahrenheit in the southeast, 21 deg C elsewhere inland and a little cooler along coastal areas, reaching between 19 to 22 deg C.
The sunshine will continue this evening but a band of heavy showery rain will push in from the southwest by around 10pm.
In the south of the country the downpours are expected to be heavy and thundery at times but as the band of rain continues to push northeastwards these showers will become lighter.
Strong winds are expected overnight along more exposed coastal areas. Gusts of around 30mph are likely.
It will be another humid night with lows of just between 16 to 20 deg C.
Friday morning will be relatively cloudy, with a risk some showers could linger, in the north.
The showers will clear during the morning to leave a largely sunny and bright afternoon.
Once again, it will feel warm and humid with temperatures reaching highs of 27 deg C, 81 in Fahrenheit.
Winds are expected to be light to moderate.
The Met Office has issued a Yellow Warning which will come into force at midnight on Saturday morning and will be valid until midnight on Sunday.
During this time, eastern areas are expected to experience some heavy, thundery downpours.
The location of these is uncertain but where they do form some torrential downpours are possible with frequent lightning, large hail and locally strong gusts.
Significant flooding is possible where these do occur from surface water as well as from small, fast responding watercourses.
The frequent lightning, large hail and strong gusts could also be an additional hazard.
